Free Strategy Games Online

Games that reward thinking a few moves ahead. Bastion Line is tower defence on islands floating above the clouds. Towers block the ground they stand on, so every one you build also bends the path the enemy walks: six towers, three upgrade tiers each, 15 isles, an Endless mode and a Daily Siege.

Deep Crypt is a turn-based roguelike with ten torch-lit floors, one life and the Hollow King waiting at the bottom. Nothing moves until you do, so every fight is a small puzzle of position and resources, with unidentified potions to gamble on and a classic ASCII view if you prefer letters to stone.

Shadow Heist runs in real time but plays like a plan. Each mansion is generated fresh; you watch guard patrols, switch off lamps, pick the vault's lock and slip out the far side. All three are seen from above in full 3D and have a daily challenge with the same seed for every player.
