About this Slot
Siege Tower Defense by Sakura Studios presents a fantasy medieval theme with an RTP of 96.2%, high volatility and a maximum win of 25,000x. The game uses Cluster Pays mechanics, where winning symbols land anywhere on the grid and tumble after each hit.
Wild symbols substitute for regular symbols during base play and bonus features. Cascading reels activate after winning clusters, dropping new symbols into empty spaces and continuing wins until no more matches form.
War tokens land during play as multipliers of x2, x3, x4, x5, x10, x20, x50 and x100. These tokens lock in place throughout tumble sequences and apply their value when a tumble sequence ends with a token-boosted win.
The Raid feature triggers roughly once in every five base spins. A raiding party crosses the table while towers shoot; killed raiders award coins, and eliminating the Captain awards a war token.
Rally triggers when exactly two Siege Banners land after tumbling. One banner-free reel redraws once while war tokens and Dragon Seals remain locked, and any third banner arrival continues the winning tumble sequence.
Battles trigger when a complete Siege Banner set forms. This tower-defence mode presents waves of enemies, lives to protect your Keep and a multiplier that increases with each wave survived. You choose tower visuals before battle starts, and kills pay according to battle rules.
Bonus buy options are available at fixed prices: Warhorn costs 2x per spin, Raid costs 20x per spin, Outpost costs 100x bet, Dragon costs 200x bet, Fortress costs 250x bet and Citadel costs 500x bet.
