About Ninja Attack

Ninja Attack puts you in the role of a ninja fighting increasingly difficult waves of ghosts. You earn rewards as you survive, but must decide whether to leave before you die or risk continuing for a chance at more.

Game modes

Classic mode has 40 waves. Survive as long as you can, then leave to collect your rewards or continue and risk losing everything. Completing Classic mode unlocks Endless mode, which goes beyond the standard 40 waves and offers greater rewards for lasting longer.

Skills and bosses

You can spend rewards from Classic and Endless modes to upgrade skills and improve your chances of survival. Every 10 waves, you face a more challenging boss ghost. Defeating it gives you a greater reward and advances you to the next tier of ghost.
