Thunder Coins XXL — Multicoin Splits & Hold
Gold thunder coins land across a 3×5 grid with fifteen paylines. Hold & Win locks coins through respins. The Multicoin Feature splits a single coin into multiple values, multiplying collection potential. Thunder Feature electrifies the grid mid-spin, transforming low symbols into higher-tier values. Modest 1,000x cap matches the conservative pacing.

Hold & Win, Multicoin Splits & Thunder Feature
Ever played a Hold and Win slot that actually kept you on edge? That's what Playson built here. Thunder Coins XXL Multicoin runs on a compact 3×5 grid with 15 Lines, but don't let the size fool you. Land 6 coin symbols in one spin, and the respin round kicks off. Each coin carries a cash value — and the Thunder Feature can zap random positions with multipliers up to 20x mid-round.
Here's what separates this from the original Thunder Coins: the Multicoin system. You're not just collecting single values anymore. Coins stack, multiply, and chain together. Four jackpot tiers sit on top — Mini at 30x, Minor at 100x, Major at 300x, Grand at 1,000x. Fill all 15 positions during respins and the Grand is yours. At 95.64% RTP with Medium-High volatility, sessions swing between quiet stretches and sudden payout bursts.

Thunder Coins XXL Multicoin FAQ
Frequently asked questions about the game
The default RTP sits at 95.64%. Keep in mind — some operators may run a lower RTP version (around 93% or 91%), so it's worth checking the info screen at your casino before you spin.
The max win caps at 1,000x your total bet. That's the Grand Jackpot, triggered by filling all 15 positions in the Hold and Win round. Not the biggest cap out there, but the jackpots hit more often than you'd expect on a medium-high volatility game.
You need 6 or more coin symbols on the reels in a single spin. Once triggered, all coins lock in place and you get 3 respins to land more. Every new coin resets the counter. Fill the entire grid for the Grand Jackpot.
Yes, 100%. Playson built it in HTML5, so it runs on any modern browser — iPhone, Android, tablet, doesn't matter. The 3×5 layout actually looks sharp on smaller screens.
The "XXL Multicoin" version adds escalating multipliers up to 20x during the Thunder Feature, plus a Pile of Gold mechanic and extra bet options. It's basically the same core loop but with stronger win spikes and more coin variety.
Absolutely. You can try the demo right here on this page — no signup, no deposit, just click play. It uses virtual credits so you can test the Hold and Win mechanic risk-free before wagering real money.
