HOLD THE LINE.
Blockhold is a pixel-art tower defense where your towers are tetrominoes.
Drop falling blocks onto the battlefield, snap them into formations, and watch
your wall come alive — every block you place is a soldier, archer, mage, medic
or cannon crew fighting to hold back the horde.
BLOCK-STACKING MEETS TOWER DEFENSE
• Real falling-block puzzling: pick from 3 offered pieces and place them smart
• Every placed block mans itself and fights — no separate "tower building" phase
• Smart-anchor placement: tap anywhere, the block finds its best fit
FIVE COLORS. ONE ARMY.
• Red Swordsmen hold the line in melee
• Blue Archers rain arrows over the wall
• Green Mages cast area arcane strikes
• Yellow Medics keep your blocks standing
• Orange Cannons blast clustered enemies
Combine colors into 4 powerful formations: Shield Wall, Arrow Rain,
Arcane Circle and Battery Wall.
A CAMPAIGN THAT TEACHES YOU TO WIN
• 30 handcrafted levels with new units, enemies and Laws unlocked as you progress
• 6 enemy types that demand real counters: swarm Infantry, armored Wardens,
heal-casting Shamans, wall-blasting Bombers, Elites and lightning-fast Runners
• 3-star challenges on every level for completionists
BEND THE RULES
• 21 collectible Laws rewrite the game: Nuke Deploy, Time Freeze, Wild Color,
Chain Reaction and more — pick one per level and break the battle wide open
ENDLESS MODE & GAME CENTER
