Build towers on your lane: they block the way and form a maze. The path can never be fully closed.
Send creeps to your opponent: every send raises your income, paid every 6 s. ×1 / ×5 / ×10 sets creeps per tap, hold to keep sending, and your last sends stay one tap away, bottom right.
Tap a tower to upgrade or sell it: at level 3, pick one of two paths.
Tap the mini-map (top right) to watch your opponent's lane.
Every creep that crosses your lane costs you a life. At 0 lives, you lose.
Attack and armor types matter: piercing shreds light armor, magic melts heavy armor, siege crushes bosses.
Place your hero (one per game): it levels up from nearby kills. Tap its skills to learn and cast them.
Research upgrades at the forge: one at a time, each takes a while.
At 5:30, sudden death: creeps get stronger every 15 s.
