Spin Stone

Spin Stone takes players back to the Stone Age, where a caveman, a tiger and a woolly mammoth lead the symbol set. Spadegaming built it on a 5×3 grid with 25 paylines, medium volatility and a 97.32% RTP, comfortably above the 96% mark many operators use as a benchmark.

The feature set is easy to follow. A stone-age cave acts as the wild, expanding wilds appear among the game’s features, and three or more scatters pay up to 500 coins while awarding up to 15 free spins. Autoplay lets players queue a set number of spins and stop at any time. Stakes run from €0.50 to €100 with a top win of €93,140, which makes it a natural pick for players who want a light-hearted theme backed by strong return figures.

Three or more matching symbols in a row on a payline produce a win. The caveman is the best-paying regular symbol at 4,000 coins for five, and the premium set as a whole pays from 60 coins for three of a kind. The A, K, Q, J, 10 and 9 ranks cover the low end, from 10 coins up to 800 coins for five.

• Expanding wilds: listed among the game’s features to help complete more lines.
• Scatter: three or more anywhere pay up to 500 coins and award up to 15 free spins.
