15 Coins Grand Platinum Edition

15 Coins: Grand Platinum Edition Overview

15 Coins: Grand Platinum Edition is a five-reel, three-row hold-and-win slot from Wazdan, released on 11 November 2024. It plays on 15 lines, carries an RTP of 96.17% and caps wins at 2,500x the stake. As with most Wazdan games, the player chooses the volatility from three settings: low, standard and high.

Our demo ran with the Hungarian interface and a stake of 1,000 fun credits, the highest step on the bet selector, so the amounts below convert to multipliers by dividing by a thousand.

Platinum Coins on a Cosmic Backdrop

The Grand Platinum editions share one look: a deep blue starfield behind the reels, dark red cells stamped with the number 15, and heavy silver coins that flash white when they land. The four jackpot plaques run along the top of the screen, and a small Grand Platinum Edition badge sits in the corner.

How the Bonus Starts

The Hold the Jackpot bonus triggers when bonus symbols of any kind fill all five positions of the middle row on the same spin. Our trigger showed exactly that: coins worth 8,000, 3,000, 7,000 and 2,000 across the middle row, closed off by a MINOR jackpot coin on the fifth reel.

All bonus symbols on the triggering spin carry into the feature, and the round starts with 3 respins. Each new bonus symbol resets the counter to three, and every symbol stays locked until the round ends.

Four Fixed Jackpots

At the 1,000 stake the plaques read Mini 10,000 (10x), Minor 20,000 (20x), Major 50,000 (50x) and Grand 2,500,000 (2,500x).

The first three arrive as labelled coins during the bonus. The Grand works differently: it is paid for filling all fifteen positions, and it replaces every other win in the round because it is the game’s win cap. That makes this a clear case of the jackpot and the published maximum being the same number – 2,500x is both the Grand and the ceiling.

The game counts down to it on screen. Midway through our second bonus the banner above the reels read, in Hungarian, that 8 more bonus symbols were needed for the Grand, with seven coins already in place.

Collectors, Cash Infinity and Mystery Symbols

The regular coins carry values of roughly 1x to 10x the stake, and three special symbols build on them.

The Collector is a small chest with a multiplier plate underneath. When it lands, it gathers the values of the cash symbols on the grid and multiplies the sum. In our first bonus an x1 collector gathered 23,000, and in the second an x2 collector showed 34,000.

Cash Infinity coins are blue instead of silver and carry values between 5x and 15x the stake. Ours showed 5,000 and 7,000. What sets them apart is persistence: they stay on the reels until the next bonus ends, and one landing on the middle row counts towards the trigger.

Mystery symbols appear as wooden chests and turn into a random bonus symbol at the end of the round. A Jackpot Mystery version reveals one of the three lower jackpots.

Chance Level and Bonus Buy

A column of Chance Level buttons on the left of the grid lets the player pay 2, 5 or 10 times the stake per spin to raise the bonus chance by at least 2, 5 or 11 times. During our bonus rounds the footer showed a total bet of 5,000 against the 1,000 stake, which fits the x5 level having been active.

A Bonus Buy menu sits behind the shopping cart button beneath the reels. Both options are unavailable in some markets, including the UK.

What Our Rounds Paid

Our second bonus finished with eleven of the fifteen positions filled, including a MINI jackpot coin, the x2 collector and both Cash Infinity coins. The two mystery chests on the middle row had turned into coins worth 5,000 and 2,000. Four empty cells stood between that board and the Grand.

Who Should Play It

15 Coins: Grand Platinum Edition suits players who already like Wazdan’s coin games and want the fullest version of the formula, with collectors, persistent Cash Infinity coins, mystery symbols and a selectable volatility.

The trade-off is a fixed ceiling of 2,500x, modest by current standards, and the Chance Level buttons, which multiply the cost of each spin quickly.
