Satoshi Spins Slot by Pragmatic Play

Before free spins even begin, a wheel appears. Gamble your starting multiplier or collect. Win and it doubles - x8 becomes x16, x16 becomes x32, up to x256. Lose and the bonus round disappears. Every spin you were about to get, gone. Each step on the wheel runs between 50% and 59% win probability depending on the tier, so it's close to a coin flip every time. You can gamble repeatedly, stacking risk on top of risk.

The tumble multiplier follows a strict doubling ladder: x1, x2, x4, x8, all the way to x1024 after ten consecutive tumbles. No random multiplier drops, no variable jumps. In free spins, this ladder starts from whatever multiplier you collected (or gambled up to), so a x32 start means your first tumble hits x64, second hits x128. Retriggers with 3+ scatters reset your spin count to 12 and push the starting multiplier up by x2 to x16, capped at x1024.

Marked symbols show up randomly on the two center reels - the widest columns at 5 rows each. If a marked symbol lands in a winning combination, it converts to Wild for the next tumble. Placement on those center reels matters because they connect the most ways across the diamond-shaped grid. A hooded figure holding a glowing Bitcoin stands beside the reels against a cyberpunk skyline drenched in neon blue and purple, with crypto-styled premiums (coins, keys, blockchain tokens) sitting above the usual card royals. Four buy options at 78x, 128x, 150x, and 288x guarantee different scatter counts, with the 128x option randomizing between 3 and 6 scatters - cheaper than the guaranteed 4-scatter buy but unpredictable. Ante Bet at 40% premium doubles scatter frequency but locks out buying entirely.
