15 Coins™

15 Coins Overview

15 Coins™ is a Hold the Jackpot slot from Wazdan, released through VoltEnt on 7 May 2023. It follows 12 Coins™ and widens the grid from 4x3 to 5x3. The logo carries both of the series’ trademarks: Hold the Jackpot and Cash Infinity™.

No Line Wins, Only the Bonus

The base game pays nothing on its own. The aim is to fill the middle row with bonus symbols of any kind, which triggers the Hold the Jackpot round. Our base-game screenshot, at a 1.00 bet, shows a Minor jackpot coin, a treasure chest and coins worth 5 and 3 already on the grid.

Jackpots

The four jackpots scale with the bet. At 1.00 they read Grand 1,000, Major 50, Minor 20 and Mini 10 – so 1,000x, 50x, 20x and 10x. At a 9,000 bet the same boards show 9,000,000 / 450,000 / 180,000 / 90,000.

Chance Level

The Chance Level panel can be off or set to x2, x3 or x5. At x5 on a 9,000 bet the total bet is 45,000. SlotCatalog describes it as an ante bet that makes the bonus up to five times more likely.

Cash Infinity and Mystery

The red Cash Infinity™ coin in our trigger screenshot carries 45,000 – 5x the 9,000 bet – next to gold coins worth 9,000 and 27,000 and a locked Mystery symbol. According to SlotCatalog, Cash Infinity coins are worth 5x–10x the bet and stay sticky until the next bonus, regular coins pay 1x–5x, and the Mystery symbol turns into a random bonus symbol when the round ends.

How the Round Plays

The published description gives 3 respins that reset with every new symbol, a collector that adds up coin values with a random x1–x20 multiplier, and the 1,000x Grand for filling all 15 positions. Our round ended on a total win of 9,009,000 at the 9,000 bet.

Controls and Bonus Buy

The bottom bar has a stake selector (our screenshots use steps from 0.80 up to 10,000.00 FUN), a shopping-cart button for the Bonus Buy menu, a chilli button for the volatility level. SlotCatalog notes that the Bonus Buy menu offers five options but is not available in every jurisdiction, and that pace and volatility each have three settings.

Numbers

SlotCatalog lists a 96.07% RTP, adjustable volatility and a maximum win of 1,000x.
