Samurai series
The Samurai series began in 2023 when iSoftbet used Samurai 888 Katsumi to fix the line's 25-payline, high-volatility foundation around free spins, fixed jackpots and reel-set changes. The first of these Samurai slots also supports bonus-buy access and additional free spins, pairing 96% RTP with a 2,272x maximum and a 0.44 to 44 bet range.

Samurai Spin Kenji carried the format forward in 2024 but changed the route to the rewards. Symbol collection, a bonus wheel and a cash collector replace the original's emphasis on wilds and direct bonus access, while reel-set changes, free spins and fixed jackpots remain. Its upper bet reaches 250, but the listed maximum moves down to 2,000x and RTP to 94.01%.
The split is access versus accumulation. Katsumi is built around reaching or buying a feature with wild-led support; Kenji asks the player to track collected symbols and cash values through a broader sequence of bonus events. Both retain a high-risk profile, but the sequel redistributes that risk across more collection steps instead of raising the reward ceiling.
