Tetrogue blends the satisfying rhythm of falling-block puzzles with the strategic depth of a roguelike. Every piece you place is a weapon — clear lines to deal damage, chain combos for devastating strikes, and watch enemies crumble as your relic build comes together.

Navigate a branching map through three stages of increasingly dangerous dungeons. Choose your path wisely: take on elite enemies for greater relics, trigger events that shift the run in unexpected directions, or conserve strength for the boss that waits at the end of each stage.

Features

• 10 unique enemy types — Every slime has its own special ability: board manipulation, status effects, and surprises that force you to adapt mid-battle.

• Playable Heroes — Choose one of 7 heroes, each reshaping how you play: guarantee the piece you need, chain unstoppable combos, or unleash a berserk rage that slows time itself. Win a run to unlock the next hero in the chain.

• 3 stages with unique bosses — Each dungeon culminates in a boss encounter that tests your relic build to its absolute limits.
  

• 50+ relics — Stack relic synergies, chain powerful effects, and forge a build that feels entirely your own across every run.
  

• Gem fusion system — Collect and fuse gems to unlock potent combat bonuses that integrate directly into your piece-placing strategy.
  

• Metaprogression — Permanent upgrades carry between runs, steadily unlocking new relics, bonuses, and possibilities for future attempts.
  

• Events and encounters — Random encounters dot the map, from risky choices to skill challenges. Some offer powerful relics, some demand a sacrifice — choose carefully.

• Infinitely scaling difficulty — Mastered the gauntlet? Climb to the next difficulty tier, or dive into Endless Mode and see how far your build can carry you.

• Challenge Runs — Optional run-long modifiers let you twist the rules for an extra challenge or a completely different way to play.

• Achievements & Tetrédex — Chase achievements and fill out the Tetrédex, a growing bestiary of every enemy you've encountered.

• Built for everyone — Full controller support, colorblind-friendly accessibility palettes, and translations in English, German, French, Spanish, and Turkish.
