Crystal Dice Review

The dice on a real casino craps table 🎲 are a work of art - for realz! They’re made to a tolerance of about 0.0005 of an inch. The pips get drilled out and filled with paint that weighs the same as the plastic that came out, so no face is heavier than another.

Each die carries its own serial number, like a banknote 💵. And they're made from transparent red plastic so anyone can look straight through and see there's nothing loaded inside.

In Crystal Dice from Amusnet Games, the Red 🔴 Dice are the ones that bust you, and the part you get to see through is the Provably Fair check you can run after every round.

Gameplay

Design has taken a backseat to functionality with this game. At the top, you'll see the usual progressive jackpots that Amusnet likes to roll out.

The 4 Jackpot Cards levels are named after card suits. From lowest to highest, they're Clubs, Diamonds, Hearts, and Spades.

Their values sit in those bars up top and grow from a slice of players' bets, and nothing gets skimmed off your own bet to feed them.

The board is a 5x5 grid of 25 face-down dice, lettered A to E across and numbered 1 to 5 down. The RTPRTP stands for “Return to Player.” The RTP describes the total bet amount that a game returns to players over millions of spins, and that figure is represented by a percentage. Table games, such as Roulette, typically have higher RTPs than many slots.

RTP needs to be considered in conjunction with a game’s volatility rate. is 96%, volatility is very high, and the max multiplier is 25,000x. The max win is $250,000. The game takes fiat currencies only, just not Japanese yen.

Every tile hides either a Green Dice (safe) or a Red Dice (the mine). Before you press PLAY (that green arrow), you set your bet and pick how many Red Dice hide on the board - anywhere from 1 to 24.

Then you hit the green button and the game tells you to select at least 1 tile to get things going. A found Green Dice glows green and bumps your running multiplier.

Hit CASH OUT whenever you like to bank the pot and end the round. Flip a Red Dice and it's over on the spot. The bet goes, and so does everything you built up in that round.

With 1 Red Dice on the board, your 1st Green Dice pays 1x, which is just your bet coming home. Thirteen Green Dice get you to 2x, and clearing all 24 Green Dice pays 24x.

Crank the selector up to 24 Red Dice (look to the right of the controls) and the lone Green Dice pays 24.25x.

Turbo Mode skips the hand-picking. You tell it how many tiles you want, it picks that many at random the moment you bet, and the round settles instantly.

It also switches off the Defuse Engine and Crystal Rush, so you're swapping the features for speed.

A Statistics menu lets you snoop on other players' recent bets, with a "Hot Streak" list of the biggest multipliers and a "High Rollers" list of the biggest payouts.

Oh, and by the way, this is also a Provably Fair game.

Features

PROVABLY FAIR:

Every Red Dice position, every safe Green Dice, every Clarity score and even the Defuse reshuffles are locked in before your first click, so the board can't shift under you halfway through.

And you don't have to take that on trust. Any finished round can be checked with the built-in Provably Fair Calculator.

DEFUSE ENGINE:

With the Defuse toggle on (top right of the screen - it’s real small), you can examine a tile before you flip it, and the game gives you a Clarity score for that tile. So that’s pretty cool, but remember, it’s not showing de facto outcomes; it’s more of a possibility.

Then you make a call. "Reveal" flips the tile as normal. "Defuse" pays a fee to toss the tile back into the board unopened. On a 0.30 bet, the fee came to 0.01.

Every unopened tile means the board gets reshuffled, but every Green Die you've already found stays where it is. The Defuse Engine is switched off in Turbo Mode.

CRYSTAL RUSH:

A 10-second timer starts the moment you place your bet. Find 3 Green Dice in a row before it runs out and Crystal Rush kicks in.

From the 4th Green Dice on, every find stacks an accelerating bonus multiplier on top of the normal payout. Each find (or Defuse) winds the clock back to 10 seconds.

Once the timer hits zero, the bonus multiplier is lost unless you cashed out before time ran out, and Crystal Rush is done for the rest of that round. It's off during Autoplay and Turbo Mode.

Look, the extra is modest. On the 1 Red Dice table, 24 finds pay 24.5x with Crystal Rush against 24x without, so racing the stopwatch earns you half a bet.

JACKPOT CARDS:

This triggers at random after any finished game, once winnings are collected, as long as your bet qualifies. It plays on top of the game and guarantees you 1 of the 4 levels.

You get 12 face-down cards and keep flipping until 3 matching suits show. That suit decides your level, and it pays whatever that level holds at that moment.

Clubs are the lowest and Spades are the highest, so you know which one to root for. Autoplay pauses while it plays out and picks back up afterward.

Performance

Everything went according to plan during my testing phase of this game.

Maximum Win

Put the max multiplier of 25,000x on the $10 top bet and the max win comes to $250,000. The minimum bet is $0.10.

Conclusion

The money comes from the Green Dice ladder, and more specifically from how many Red Dice you're brave enough to put on the board. With a few Red Dice, the climb is long and slow. Pile them on and it gets short and steep.

Jackpot Cards are a random extra, nice when they show up, but not something to build a plan around.

Here's my own back-of-the-envelope math, not a game claim. With 1 Red Dice, the opening flip risks a 1-in-25 bust to pay 1x, which is zero profit.

With 24 Red Dice, the one safe die is a 1-in-25 shot at 24.25x. Clearing a whole 1 Red Dice board is also 1-in-25, and it pays 24x.

At both extremes the house keeps about 3 to 4 cents on the dollar, which lines up with the 96% RTPRTP stands for “Return to Player.” The RTP describes the total bet amount that a game returns to players over millions of spins, and that figure is represented by a percentage. Table games, such as Roulette, typically have higher RTPs than many slots.

RTP needs to be considered in conjunction with a game’s volatility rate.. All that changes is the shape of the risk.

The Defuse Engine is a paid second look at a tile. You pay the fee every time, and Clarity isn't defined as an exact probability, so I'd call it a comfort purchase more than an edge.

The game suits players who like steering their own risk and quitting on their own terms, provided they pick a cash-out point before the first flip and actually take it.
