Tetrogue

Tetrogue combines falling-block puzzles with roguelike strategy. You place pieces to clear lines and damage enemies, chain clears into stronger attacks, and assemble a build from relics as you fight through dungeons.

Dungeon runs

Each run follows a branching map through three stages of increasingly dangerous dungeons. Choose whether to face elite enemies for greater relics, trigger events that can change the run, or conserve your strength for each stage’s boss. Random encounters offer risky choices and skill challenges: some provide powerful relics, while others demand a sacrifice.

There are 10 enemy types, each with a special ability such as manipulating the board or inflicting status effects. Each stage ends with one of three bosses, drawn from nine in total, including the Minotaur, the Trickster, the Elder Dragon and the Spider Queen. Bosses have their own attacks and change tactics as their health drops.

Heroes and builds

You can play as seven heroes, each with a different effect on how you play. Ivy gets the long piece when a quad clear is ready; Olaf fuses gold squares; Turner rewards spins; Jonas strikes through Hotlines; Link chains clears up to x10; Zoro goes berserk; and Sabrina casts spells from magic crystals. Win a run to unlock the next hero.

More than 60 relics can be combined into builds, with effects that work together across a run. You can also collect 15 kinds of gems, socket them according to clear size, and fuse matching gems into rarer tiers. Gem effects include a sword sweep that hits every enemy, poison, slowing, critical hits and gold. Permanent upgrades carry between runs and unlock relics, bonuses and options for future attempts.

Modes and multiplayer

As difficulty scales, you can move up to the next tier or try Endless Mode to see how far your build lasts. Twelve optional Challenge Run modifiers change the rules for an entire run; in Turn Based, for example, time moves only when you place a piece. Boss Rush pits you against every boss back to back as you chase your best time, while the Lab lets you set up battles to practise against a boss or test a build.

In local or online multiplayer, one player fights through the dungeon while the other commands the enemies. The second player upgrades them before each battle and attacks from their own board.
