Build towers along the trail and stop a parade of slimes before they reach the castle.
Slimes pour out of the cave and wobble down the trail toward your castle. Build arrow, bomb, frost and spark towers on the stone pads, upgrade them twice each, and hold the line through every wave. Fast slimes, armoured slimes, flying slimes, healers, tanks and splitters all need a different answer, and the Slime King waits at the end.
Eight maps unlock one after another: S-bends, spirals, crossing trails, two separate roads and a long maze. Call waves early for bonus gold, speed the game up when you are confident, and earn up to three stars on each map.
Tap a stone pad, pick a tower and tap it again to build. Tap a tower to upgrade or sell it. Start each wave when you are ready; slimes that reach the castle cost lives.
