Wheel of Amp

Red Tiger gave Wheel of Amp a steampunk look: a plush living room aboard an airship, with other craft drifting in the sky outside. It begins as a small 3x3 grid with 9 paylines and grows over time. Reels and rows are added one at a time, alternating between the two, until the board reaches 5x5 with 25 paylines. Early on only three-of-a-kind wins are possible, then four, then five.

The low symbols are everyday period gadgets: pens, telegraph keys, telephones, gramophones and old cameras. Premium transport symbols, such as a velocipede, a plane, a car and a train, are absent at the start and are unlocked one by one. Five of a kind among them pays 4.5x to 10x the stake. There is no wild.

The central feature is the Wheel of Amp, set off by three wheel scatters anywhere in view. The player spins a wheel that can award free spins, a Win Boost multiplier or a Step Change. The wheel starts with eight Step Change segments, half unlocking premium symbols and half adding a reel or row, and once one has been used it becomes a Win Boost segment. A boost is kept until the next win and then applied to it. The starting boost is 10x, and unlocking premiums adds x2, x3, x5 and x6 segments, with more arriving as the grid grows.

The free spins segment awards 10 spins. The wheel can be triggered again inside them, and free spins won that way add 5 more. A Win Boost gained here stays active for every win in the round and for the first win after it ends back in the base game.

The RTP is 95.77% and volatility is rated 5 out of 5, with a hit frequency of 3 out of 5. Prizes top out at 7,303x the stake, and bets range from 0.10 to 10.
