A medieval army marches a winding road through your fields, and your keep has 20 hit points and absolutely no interest in giving any of them up. Three tower types and a deployable bomb cover every threat: Archer towers fire rapidly at the furthest target, Bombard towers lob devastating single-target shells at anything heavily armored, and Frost towers fire slowly but burst on impact into an area-of-effect chill that slows every enemy caught in it. When a wave threatens to break through, select the Bomb, tap anywhere on the battlefield — even right on the road — and drop a one-time blast that deals heavy area damage with falloff from the center.
Every tower upgrades twice. Upgrades raise both damage and fire rate, not range — so upgraded towers hit harder and faster from the same position, and upgraded Frost towers chill a wider area for longer. When your keep takes damage, the Repair button restores 3 HP for $100, though it tops out at 20 HP no matter how often you use it. Waves grow harder every round: light skirmishers arrive at wave 3, wheeled battering rams at wave 6, and an armored war elephant with an escort every fifth wave. Tower Defense is an original game made for GameMyself; it plays with mouse or touch in any modern browser, no download, and your best wave is saved only on this device.
