Pick a gate, grow your army, smash whatever is in the way. Each run you steer a crowd of soldiers down a long road. Gates add or multiply troops, or turn soldiers into shield bearers, archers, giants or mages. The enemy groups ahead show what beats them, so you can plan before the clash: shields stop arrows, archers take down towers, giants break barriers and armor, mages clear swarms. Watch out for hammers, saws, holes and narrow bridges. Hold the button to squeeze your army into a tight line and get past them. Every fifth level ends with a boss. Each boss has a weak spot and a class that hits it harder. Between runs you can build up your island kingdom. Buildings make your troops stronger and farms make gold while you are away. Skeletons attack the kingdom from time to time, and you aim the tower arrows yourself to hold them off. 30 levels across 3 worlds (Green Meadows, Mushroom Forest, Frozen Peaks) with 6 bosses, plus extra levels after each world.
