Only Coins Slot by Gamzix

Collect sweeps left to right, then the Walking Multiplier doubles whatever it gathered. That interaction is the core of Only Coins, and it's the difference between a modest bonus round and one that actually reaches toward the 2,000x ceiling. The Collect symbol picks up every visible coin value on the grid - regular prizes, Jackpot coins, Sticky Mystery reveals, even other Collect symbols that already accumulated their own totals. If the Walking Multiplier Frame happens to sit on the same position that spin, it waits for the Collect to finish its sweep before applying the x2. Timing matters here more than in most Hold The Spin games.

There are no regular symbols on this grid. No cherries, no card royals, no wilds. Every reel position is either empty (dark blue cell against a neon Vegas skyline) or holding a gold coin with a bet multiplier between 1x and 9x. The middle row is the trigger row - fill all five positions with coins and the bonus activates, transferring those coins into a 15-cell respin board. From there, each empty cell spins individually, and any new coin resets the counter. Sticky Mystery coins lock in place and only reveal their value at the end, which keeps you guessing whether that locked position holds 1x or a 50x Jackpot. Four fixed tiers sit on the left sidebar: Mini at 10x, Minor at 20x, Major at 50x, and the Grand at 500x for filling every last position on the board.

At 30x your bet, the buy bonus forces an immediate trigger. But the Heap of Coins feature adds a random path in too - any coin landing in the base game has a chance to dump enough extra coins onto the middle row to start the bonus without waiting for a natural fill. The pile of gold and gems stacked above the reels is decorative only, though. Doesn't affect trigger odds, just looks expensive.
