Eagle Riches

Eagle Riches, developed by Red Tiger, is a slot machine that comes with a theme going around animals of Wild West. It contains 5 reels and 4 rows. The machine has been set against a magnificent red mountainous terrain, and it offers players a chance to enter the amazing jungle safari.

The gamblers meet giant buffalo, humble sheep, and other wild animals of the kingdom. While on their way, they pray for the appearance of the eagle again and again, as this mighty bird can open doors for many rewards and hidden treasures. The machine comes with 40 playlines and thus offers a huge number of ways for the players to score a win.

Machine Graphics

Red Tiger has definitely produced a machine for ages if one were to go by the graphics. The game symbols have an unmissable golden hue, perhaps a subtle hint for all the treasure held within. The transition effects are smooth and at par with any other machine developed by providers like Microgaming and NetEnt. The theme music has been composed by in house creators of Red Tiger. It perfectly fits the game setting, and punters feel a sense of thrill as they go on an adventure into the wild.

How to Play Eagle Riches?

Red Tiger has been known for keeping things simple. Betting in the slot is just a matter of a few clicks. But before that, let's explore all the amazing features that a player would be treated with. Eagle Riches comes with free spins, wild cards, and multiplier wins.

Major Symbols

Being an animal-themed game, all the symbols used in this game pay tribute to the animals.

  • The Eagle is the highest paying symbol in the game. It awards 800 coins if 5 of these symbols appear on the reels.
  • The Buffalo is the 2nd highest paying symbol and players are awarded 500 coins for 5 of these symbols.
  • Next in the line is the fiery wolf that awards punters with 300 coins, if 5 such symbols are present.
  • Sheep and cat come last when it comes to special symbols. The sheep pays players 220 coins while the cat pays them 180 coins.

The regular symbols used in the machine are A, K, Q, J, and 10. They are low-value symbols, although each of them appears to have been dipped in molten gold.

Wild Symbol

The mighty eagle acts as the wild card in the game. It replaces any other symbol if it leads to a big win for the gamblers. By going to the paytable, the punters can watch an animated demo of this and understand how it works. Alternatively, they can play free Eagle Riches slots, available on our site to understand the working of the wild card.

Free Spins

There is an incredibly powerful card present in the game. It has 'Eagle Spins' written in golden on it. If this card appears on reel numbers 1, 3, and 5, the players are awarded 10 free spins. During the free spin rounds, the Eagle Spins card remains locked in their position, and hence it increases the chance of further wins for the punters. This also explains why Red Tiger has named this game as Eagle Riches. The eagle definitely opens the door for many amazing riches and rewards.

Placing Bets in the Slot

Slot machines have become popular because unlike other gambling options, it is really easy to place a bet in slots. Red Tiger has followed the suite and made betting in the machine a matter of few clicks. So before you ride into the wild with your favourite animal, here is how you can place your wager.

Button Function
StakeMostly slot machines use the 'Coin' button, but the developers of this game have decided to go with the 'Stake' button. Nonetheless, the function of this button is to provide a betting range. Using this button, the punters can select a suitable stake. The minimum value is 0.20, and the maximum value is 40.0. Punters are advised to check their stakes before they play as the default has been set at 2.0.
SpinOnce the stake size has been decided, gamblers need to press the circular spin button to tumble the reels. This button is present at the rightmost corner of the main screen.
TurboNormally, slot machines are designed for being enjoyed by the players of all age groups. Hence the speed of reels might appear a bit slow to our young players. To solve this problem, Red Tiger has provided the 'Turbo' button. This button helps the players in speeding up the reel's pace.
AutoplayFor players who want to enjoy an uninterrupted gambling session, without having to press spin again and again, the 'Autoplay' is the best option. It helps the players in deciding the number of spins they want to have without any break as well as place a stop loss for the autoplay rounds.

Players are advised to always have a stop loss in place so as to avoid rude shocks of huge losses.

Winning in Eagle Riches

In order to win in this game, the players need to have 3 matching symbols or have a wild card to assist them in forming a winning combination. All the wins in the game are counted from left to right. If the players have a winning combination on more than one line, they are paid for the highest paying playline.

Once the punters press the spin button, they effectively give up the control of things. The outcome of the reel is decided by the RNG algorithm. This mechanism is responsible for keeping things fair and makes winning in slot machines a matter of luck.

Strategy to Win

When we tell you that winning in slot machines is a matter of luck you need not be disheartened. With some practice in the demo games and a proper slot strategy, you can make your own luck in the slot machines. Here is how:

  • Before signing up at any online casino and playing with your hard-earned money, make sure that you have had enough practice in the demo games. With proper practice, you can understand the payout range and jackpot mechanism much better.
  • Begin the game with a small wager to understand whether the machine is running hot or cold. A hot machine is known to produce wins, while cold machine just eats the wager and make losses for the players.
  • When opting for an autoplay mechanism, always place a stop loss to avoid huge losses.

Board Cutouts

Board cutouts are commonly used to indicate a non-plated region of the board that can be removed. See Board Outlines for additional details on this style of cutout.

For Eagle, these should be drawn on the Dimension layer using the Wire or Line tool. Simply draw the edge of the area that you want removed. Board cutouts have a minimum width of a 68mil (1.7272mm), which is the size of the tool used to fabricate them.

Cutouts that are drawn over copper features (traces, holes, etc) are not supported, but may work.

Important Notes about designing Slots in Eagle

Eagle does not have internal support for slots. This has several consequences for designers:

  • Eagle’s DRC checker have several situations where slots are not checked.
  • Eagle can not export a “drill slot” file directly.
  • Lots of inconsistency in how slots are indicated with existing designs and footprints
  • Fabs may have special requirements for how to export slots

As a result of this, getting guaranteed slots requires special attention to avoid design or fabrication issues.

Important Notes about ordering Eagle slots

We have full support for NC Drill files that include slot data. However, Eagle has no way to produce slot data in NC Drill files. As a result, designers wanting guaranteed slots can do the following to opt-in to an automated workaround in our process:

  • Drawing the slot as described below using the Milling layer.
  • Verifying certain DRC aspects which Eagle does not account for.
  • Ensuring that the Milling layer does NOT contain legacy slot drawings or non-slot data
  • Ordering using gerber files generated using our Slot Path CAM job below
  • Ensuring that our site generates a Detected Supported Slots note on the upload.

These requirements are to avoid various issues with Eagle’s DRC, conflicts with existing designs using the Milling in unexpected ways, and our own file cleanup of drill files.

OSHPark Eagle tools

Our OSHPark Eagle Tools Eagle script will install the appropriate CAM jobs, as well as help update them if anything changes.

If you already installed this, you can simply Update and the script will add the new CAM jobs.

Eagle 7.1 and older
Eagle 7.2 and newer

Verify All Internal layers!

When using Slots with a 4 layer PCB, you MUST manually verify internal layers. Eagle’s DRC does not respect any method of making slots, and copper pours or auto-routed traces will short to the slot.

To resolve these issues, you’ll need to use Wires to replicate the copper being added to the Top and Bottom layers for your slot.

Standard Slot Restrictions Apply

In addition to Eagle quirks and restrictions, slots must comply with standard support requirements as noted here: Slot Support

Drawing Eagle Slots

Plated Slots

At minimum, a slot requires the following:

  • Copper beneath the entire slot
  • A valid annular ring on all parts of the slot
  • A line representing the slot path and slot width on the Milling layer.

The easiest way to draw slots in Eagle without unexpected issues is to do the following:

  • Add 2 Vias, representing the start and end of the slot. Set the Drill property set to the desired slot width.
  • On the Milling layer, draw a line between the center of each via. Set the Width of this line equal to the slot width.
  • On both Top and Bottom layers, draw a Wire between the center of each via. The Width of this line typically would match your Pad size, but at minimum must be (slot width) + 2*(annular ring)
  • For 4 layer boards, draw 2 additional Wires on the internal layers to connect traces. It’s recommended to ensure the Net is correct.
  • On the tStop and bStop, draw 2 more lines between the via centers. The Width of these lines should be the same as the copper. Optionally, you can make them up to 4mil (0.1016mm) wider to account for mask expansion.
  • Export the gerbers using our CAM job with slot support.

The end result is 5 lines which all have the same start coordinate, same end coordinate, and a via on both start and end coordinates.

Plated Slots in Footprints

Plated slots can also be created using a Long Pad inside component footprints. This is similar to the above, except that the Pad object automatically generates the required copper, tStop, and bStop layers.

Notes about this approach:

  • Long Pads can only be created as parts of component footprints. For slots not in a footprint, use our other recommended method.
  • The properties of copper on Long Pads is dependent on the DRC settings in the Shapes tab. Unexpected changes in this tab can potentially result in slots being fabbed in unexpected ways.

Non-Plated Slots

Non-plated slots have the following requirements:

  • Must NOT have copper below the slot
  • A line representing the slot path and slot width on the Milling layer.

The easy way to represent this in Eagle without issues is as follows:

  • Either load our DRC file, or verify that the DRC setting Distance > Copper/Dimension is greater than zero. We recommend 15 mil (0.381mm) for our service. If this setting is zero, Eagle will not remove copper from beneath the cutout, which will result in the slot being plated.
  • Draw a line on the Dimension layer, with the start and end coordinates representing the start and end of the slot. Set the Width equal to the slot width.
  • Draw an identical line on the Milling layer. It should have identical start and end coordinates, and the same Width.
  • Export the gerbers using our CAM job with slot support.

The two different layers have different purposes:

  • Milling is used to indicate the slots during CAM export and our processing. However, it does NOT interact with Eagle’s DRC.
  • Dimension is used to apply DRC rules to the slot. This is most notable on copper pours near the slot.
  • Dimension also serves to provide legacy data for other fabs and CAM jobs.

Alternative Non-Plated Slots

Some users or designs may wish to continue using the “cutout” or “boundary” style Dimension layer, but also want fully supported slots. This is not an issue.

To do this, simply

  • Draw the slot boundary on Dimension. The center of this line should represent the board edge. The line width should generally be 1mil (0.0254mm) to 10 mil (0.254mm).
  • Draw a line on the Milling layer, with the start and end coordinates representing the start and end of the slot. Set the Width equal to the slot width.
  • Either load our DRC file, or verify that the DRC setting Distance > Copper/Dimension is greater than zero. We recommend 15 mil (0.381mm) for our service. If this setting is zero, Eagle will not remove copper from beneath the cutout, which will result in the slot being plated.
  • Export the gerbers using our CAM job with slot support.

Notes about this approach:

  • In case the Milling and Dimension layers are misaligned or mismatched, we make no guarantees about which layer is treated as “correct”.
  • The Width of the Dimension lines alter how Eagle applies the Edge Keepout spec. This is most notable near copper pours. Eg, a 10mil dimension line removes more copper than a 1mil line does.

FAQ

Do I need to adjust my existing designs?

Nope! Read the next question for details.

Can I just upload my old stuff as always?

Yep! Legacy slot support remains unchanged. This means that (most) slots are unsupported but will usually work.

The only previously supported slot type is non-plated cutouts at least 68mil wide, and indicated as a “board cutout” or as a slot path on Dimension. This will continue to be fully supported.

If you need the old documentation for some reason, it’s now located here: Legacy Slots

Do I need to use the new CAM?

Yes. This is to ensure that the designer has verified the correctness of their design, and that their Milling layer properly represents slots as we expect them.

We feel this is important since Eagle itself does not have a proper process for slots. Trying to make slots in Eagle means granting electrical connectivity to a non-DRC verified layer (Milling). This can result in uncaught errors, which can destroy a board, and potentially any equipment plugged into it.

Eagle Slot Car

What happens if I upload a .BRD file or use a different CAM job?

Your slot will be treated as all legacy slots are. This means your slots will not be guaranteed, but will usually work.

Our legacy CAM jobs and BRD upload use both Milling and Dimension for the outline layer. This means

The instructions we provide will generate a “slot path” on the board outline when used with other CAM jobs or when a .BRD file is uploaded.

Can I use these instructions to get slots from other fabs?

Probably! We’re not doing anything radical: the Dimension and Milling layers have been used this way for years.

We’re just offering support to one of the many ways these layers are used, with the hope that it makes things simpler, more consistent, and more robust.

Why don’t you just make a new custom layer for slots?

Eagle Slot

We considered it, but it’s not a great idea.

Milling is historically used for milling/slot data, and this is known by most designers. This means anyone editing a design will look here for slot info.

Eagle Slotted Hole

However, it’s easy to miss custom layers, especially if a designer does not work with us regularly. This means someone editing a board may inadvertently adjust the board without adjusting the slot data. This would result in parts missing slots, or slots appearing where they shouldn’t.

A new layer would also remove all backward compatibility with other processes.

Do you have examples?

Yep! See this attachment, which provides a fairly comprehensive way of using slots and milling in Eagle.

What about drawing it like __ ?

We’d recommend the above approach instead. There’s lots of ways to draw things in Eagle, but most of them have issues or shortcomings that make them unreliable. Our slot reference includes several examples of slot styles we’ve seen, as well as some problems that turn up when using them.

I need to use drill slots with other software/fabs. How do I do that?

Easily! We planned for this.

  1. Use our CAM job
  2. Open the .slotdrills.xln file in Gerbv.
  3. Go to File > Export > Excellon Drill.
  4. Select the .slotdrills.xln file, and click OK.
  5. Close Gerbv, and re-open the .slotdrills.xln file to verify things

Done! You now have a true drill file with slots.

Note, however, that not all versions of GerbV support slots. If you re-open the converted file and there’s no slots, this is likely the case.

Can I avoid this by just using holes?

Certainly! In a lot of cases, you can just use holes instead of slots. Just make the diameter of your Hole or Via equal to or larger than the original length of the slot.
