1Pick a tower from the shop and tap an empty spot next to the path.
2Drag a tower onto a twin of the same kind and level to merge them. Drag it to an empty spot to move it.
3Tap a tower to see its range, choose what it aims at, or sell it.
4Balloons have layers. Lead needs a bomb or a level 4 sharp tower; black ones shrug off bombs, white ones ignore glue.
5Every balloon that gets through costs lives. The menu button pauses the game.
About it
Balloons float along a path drawn on graph paper, and you stop them with towers made from stationery: a Pencil Darter, a Compass Spinner, a Stapler, a Glue Squirter, a Ruler Sniper and an Ink Bomber.
There are no upgrade menus. Drag a tower onto another of the same kind and level and they merge into one a level higher, up to level 6. Higher levels shoot faster, reach further and pop tougher balloons.
Three pages to play, from a long lazy path to a short dash where every tower counts. Survive 40 rounds to win, then keep going for a high score. Your run is saved, so you can leave and come back.
Two towers of the same kind and level merge into one a level higher.
