Coin Fusion: value coins, respins and a widening grid

Coin Fusion is Mancala's take on the coin slot: a grid that opens at three reels by three rows, no paylines, and coins that pay the number written on them wherever they stop. Its main event is a respin Bonus Game, started through the Mystery vault, during which the grid can widen to seven reels.

From the Mystery vault to the bonus

At most one Mystery vault lands per reel. Behind its door waits either a coin or the blue "+1" disc called Respin Trigger, which has no other source. One such disc raises the respin counter by a single step, with six as the ceiling, and launches the Bonus Game. Neither Mystery nor Respin Trigger plays a part once the bonus is running.

Respins, lives and the Collector

The bonus begins on the 3x3 grid. Each newly landed symbol resets the respin counter to its starting figure; Mystery results collected in the base game can push it as high as six. The Double medallion, which only lands beside coins and doubles the coin values on screen, carries lives inside the bonus: each life it loses costs a respin and restores the counter, and with the last life gone the symbol vanishes. The Collector piggy bank, a bonus-only symbol, gathers the coin values a single time.

RTP is absent from the table because each version a studio releases carries its own value. The Mancala provider page holds the rest of the studio's lineup, and every other maker is listed in the provider directory.

Wider reels and the Magic Reel offer

Each time a reel fills top to bottom with coins or other eligible symbols, the grid adds a reel, up to seven. Fill the entire grid and an offer appears: pay a quarter of the current winnings to spin a Magic Reel of three cells. Possible outcomes are five jackpots, three fixed prizes or an empty cell. The board above the reels names them, in multiples of the stake as the game screen shows: x100 for Mini, x500 for Minor, x5,000 for Major, x10,000 for Grand, x25,000 for Ultra.

Screen layout

A blue-violet hall framed by arches of bulbs surrounds the reels. The piggy-bank logo sits on the left above the "+MYSTERY" switch, off by default; this is the HyperPlay from the rules, which makes Mystery vaults more frequent and raises the stake by 25%. BUY BONUS, the yellow button top right, purchases the respin bonus at 100x the stake, with as many as six respins inside. The right edge carries the spin, autoplay and stake controls.

Free play, then real money

As with most titles in the slots catalogue, Coin Fusion opens in a free mode without a stake.
