15 Coins Grand Diamond Edition

Inside the game

Captured in the studio's own free demo on 12 September 2026. Nothing below is taken from a press release or another site — it is what the game shows when you open it.

The base gameThe Grand Diamond Edition mid-round: fifteen independent reels on a grid of 3 rows and 5 columns, with two coins at 600, one at 480, one at 240, two chests, a MINI, and the two closed cards — the green Mystery and the blue Jackpot Mystery. The jackpot ladder runs vertically here, to the right of the grid: GRAND 300,000.00, MAJOR 3,000.00, MINOR 1,200.00 and MINI 600.00 FUN for a total bet of 60.00. On the left Chance Level sits on OFF, with x2, x5 and x10 below.
Game rules, page 1Cash Out, the feature that belongs to this edition: a Cash Out label lands on a random reel and sticks to it for up to 20 spins, accumulating the value of every Cash, Cash Infinity or MINI, MINOR and MAJOR Jackpot symbol drawn on that reel. When the countdown reaches 0 a percentage is drawn at random — from 10% to 100%, then 150%, 200% or 300% — and that share of the accumulated sum is paid out; the thumbnail shows the draw stopping on 300% for 230.
Game rules, page 2The Bonus symbols page: five of them are needed, of any type, on the middle row of the reels to open the Hold the Jackpot bonus game — the thumbnail shows the full row, two red Cash Infinity symbols and three gold coins. Below, the line specific to this edition: Bonus symbols pay only in the Bonus Game, or when they have been accumulated by the Cash Out label.
Game rules, page 3The Cash Infinity symbol, shown here at 840 on a coin with a red diamond core: it can land in the base game, sticks to its reel and stays there until the end of Hold the Jackpot. In this edition it is worth 5x to 15x the bet, paid only at the end of the bonus game, and on the middle row it raises the chance of triggering that bonus.
Game rules, page 4Entering Hold the Jackpot: the round is played on fifteen reels and every Bonus symbol sticks to them. Three re-spins are granted at the start, each new Bonus symbol resets the counter to 3, and the round ends when the re-spins run out or all fifteen reels are filled.
Game rules, page 5What the symbols are worth during the bonus game: a Cash coin pays 1x to 10x the bet, twice the scale of the original version. The three jackpots shown carry their multiple underneath — MAJOR 50x, MINOR 20x, MINI 10x — appear at random during the bonus, and several jackpots of the same type can be won in one round.
Game rules, page 6The Collector and the two Mystery symbols. The first gathers the value of every Cash and Cash Infinity on screen and multiplies it randomly by 1x to 20x — the thumbnail shows it swallowing 10, 7, 15, 3 and 4 to display 780. Below, the green Mystery turns into any other Bonus symbol except a Cash Infinity, and the blue Jackpot Mystery only into MINI, MINOR or MAJOR; both open one by one at the end of the bonus game.
Game rules, page 7The end of the bonus game: the prize is the sum of the Bonus symbol values, MINI, MINOR and MAJOR jackpots included — unless the GRAND lands. Collecting all fifteen Bonus symbols awards the GRAND Jackpot, 5,000x the bet, shown here as 300,000.00 FUN; it is the maximum prize in the game, and symbol values are not added to it.
Game rules, page 8Chance Level, a setting left to the player: on OFF the game runs at the base bet; set to x2, x5 or x10 it multiplies the bet by that much. The stated gains in chance do not follow the same scale — at least 2x on x2, at least 6x on x5 and at least 13x on x10. The panel notes that the paytable is untouched: symbol values stay those of the base bet.
Game rules, page 9The disclaimer page, where the game states its own ceiling: the maximum win is 5,000x the bet. It also notes that the paytable reflects the current bet configuration, that every round is independent of the last, and that a sticky symbol tells nothing about how the remaining symbols will land.
Game rules, page 10The rules summary, with a screenshot of the game in play: fifteen independent reels on a 3x5 grid, no prize outside the Bonus Game or the Cash Out feature, five Bonus symbols on the middle row to open Hold the Jackpot, and a maximum win of 5,000x the bet. In the thumbnail, at a total bet of 2.00, the GRAND reads 10,000.00, a Cash Out label counts 14 spins for 12 accumulated, and the win counter stands at 2,480.00.
Game rules, page 11The same chapter as a list: the three re-spins, Cash coins worth 1x to 10x the bet, the Collector, the two Mystery symbols, and the GRAND Jackpot at 5,000x the bet. One point is added — the bonus game is played at the bet level and Volatility Level of the spin that activated it. Then the Chance Level section begins, with its three steps.
Game rules, page 12Further down the page, where the game gives its return to player: 96.15%. Above it, the Extreme and Double Extreme Volatility note — two volatility settings on which the Buy Feature can open Hold the Jackpot. Below, the main game controls section begins, with the blue play button and the autoplay menu.
Game rules, page 13The button page: the autoplay menu stops the run on any win, on entering a bonus game, or as soon as a win or a change in balance passes a set amount. Then come the four ways to change the bet, the Win and Total Bet counters, the balance, and Gamble, which puts the win back in play for a chance to double it.
Game rules, page 14The end of the icon list: sound and music mute separately, the rules and the paytable each have their own button, and the game history is available only when playing for money. At the bottom the Volatility Levels section opens, the setting through which the studio lets the player choose a game style.
