How It Works

Simple rules.
Deep skill.

01
Stack Pentominoes
Place 5-cell pieces on a 12-wide board. Clear full rows — called Bands — to score and advance.
02
Climb the Tiers
Every 2 Bands you tier up. Higher tiers unlock harder pieces, faster speeds, and bigger score multipliers.
03
Race the Clock
5 minutes. Same seed for every player. No excuses — the leaderboard measures pure skill.
⚡
Reserve Mechanic
At Tier 5, unlock Reserve — hold a piece and swap it when the perfect moment comes.
🎯
Pentris Bonus
Clear 5+ rows at once for a massive Pentris bonus — the highest-skill move in the game.
🔒
Seeded Fairness
Every session uses a shared seed. Competitors face identical piece sequences — pure skill decides the winner.
📈
Ranked Brackets
Progress from Newcomer → Intermediate → Advanced → Master. New pieces unlock as you improve.
