Tetranea

About

Tetranea looks like a simple tile-placement game. It's not.

It's a deep roguelike deckbuilder where every run challenges you to build the perfect card synergies, outsmart unique bosses, and master advanced scoring techniques.

• 196 unique cards including 91 base shapes plus modifiers (rotate, flip, multiply, clear, fill)
• 44 special ability cards that transform how you play
• Reward system: modify cards, delete weak ones, duplicate powerhouses, increase hand size
• 13 unique bosses with game-changing mechanics
• Procedurally generated runs, every game is different

The basic mechanic is simple: place tiles, fill rows and columns on a 9×9 grid. But mastering Tetranea means learning to chain bonuses:

• Score multiple rows/columns simultaneously
• Trigger intersection combos
• Build multiplier stacks
• Achieve perfect symmetry patterns
• Navigate blocker tiles strategically

Casual players won't notice the depth. Strategic players will spend hours optimizing their decks.

• Short, long, and infinite run modes
• Multiple difficulty settings
• True roguelike difficulty, the hardest runs require both strategy and luck
• What you learn carries forward, even when you lose

• No ads, ever
• Core game completely free
• One optional purchase unlocks infinite mode and harder difficulties
• No timers, no energy systems, no predatory monetization

If you love Slay the Spire, Balatro, or deep strategy games that respect your time and intelligence, Tetranea might be your next obsession.
