Wallbarrow: Maze Tower Defence

Maze-building tower defence: lay walls to stretch the enemies' march into a long serpentine, then raise them into arrow, frost and cannon towers. Three maps of 20 waves. Free, no ads, no tracking; tap or keyboard.

There are no fixed lanes in Wallbarrow. Enemies march from the gate to your keep by the shortest route across open ground, and every wall you lay changes that route. Stretch it into a long serpentine, then turn the walls along it into towers.

Any wall that would seal the path completely is refused, so the maze is always open: the craft is in making it long.

• Maze building: walls cost 5 gold; the shortest path is recomputed by breadth-first search after every change and drawn on the field
• Three towers, three levels: arrow (fast), frost (slows), cannon (splash, ignores armour)
• Five enemies: grunts, quick runners, armoured shields, brutes and a crowned boss on waves 10 and 20
• Three maps: Chalk Down, Barrow Ford with a rock ridge and one ford, and Twin Gates with two spawns
• 20 waves per map: gold for kills and for each held wave, bonus gold for calling waves early
• Speed x3 and a sell tool: rebuild the maze when the waves change
