Tetrabeasts

The winds of change are blowing. Savage monsters have risen from the wilds and rallied under your command to conquer the human realms. As their general, forge living tetromino battle lines and shatter enemy fortifications.

A Falling-Block Battle for the Fate of Your Warband

Tetrabeasts fuses classic falling-block puzzle gameplay with intense tactical monster combat. Deploy unique living tetromino units onto the battlefield, clear rows to unleash coordinated assaults, and smash through enemy strongholds before your warband is overwhelmed.

Every block is a living warrior. Each monster unit carries its own health, attack power, role, passive abilities, and special gauge. Brutal attackers deliver raw power, unbreakable tanks anchor the line, and healers keep your forces alive amid the chaos.

Clear Rows. Shatter Castles. Survive the Onslaught.

Filling a row doesn’t just clear the board—it triggers a devastating attack based on the exact monsters in that line. Every clear also charges your Commander’s powerful ultimate ability.

The enemy strikes back without mercy. As your campaign intensifies, human assaults grow faster and more brutal—destroying your units, draining your reserves, and punishing every mistake. Adapt or fall.

Build Your Run

Choose from five unique Commanders, each with a game-changing special ability—from resurrecting fallen units and slowing time to shielding the board or transforming the bottom rows into an unstoppable assault. Pair them with 2–4 monsters selected from nine distinct beasts, each bringing powerful passives to the fight.

Between battles, shape your campaign with 36 run modifiers, 16 level modifiers, and 8 upgradable permanent shop buffs. Unlock new monsters, collect cosmetic skins, and experiment with wildly different strategies: glass-cannon aggression, ironclad defense, special block synergies, or high-risk modifiers for massive rewards.

Special Blocks and Epic Boss Battles

Turn the tide with game-changing special blocks: Bomb, Lightning Bolt, Earthquake, Death, and Slow Gravity. Deploy them at the perfect moment to clear space, protect your army, or deliver the killing blow.

Boss encounters crank the pressure to the limit. Each boss unleashes dangerous abilities—bombarding your lines, laying deadly traps, or reinforcing their own defenses. Underestimate them at your peril.
