LEVEL 01 · STREAK

The streak
is sacred.

Every day Eigen drops fresh math and physics problems. Solve at least one and the flame lives another day. Streaks don't touch your rating — the flame is its own trophy, and everyone can see whose is still burning.

68day streak
  • 🗓Daily questions — a fresh drop of math & physics problems every single day.
  • 🔥Keep the flame alive — one solve a day is all it takes. Miss it, and everyone on your rivals list gets notified.
  • Separate from rating — streaks measure discipline, the arena measures skill. You'll want both.

LEVEL 02 · RAID

Build walls. Break walls.

Your profile isn't a page — it's a fortress. Stack it with the hardest problems you own. Then go siege someone else's.

⚔ OFFENSE

Raid a rival's question wall. Every problem you solve cracks a brick. Clear the wall and you loot rating and eternal bragging rights.

ENEMY WALL · 5/12 BRICKS DOWN
🛡 DEFENSE

Defend your wall

Curate a wall of problems so brutal nobody clears it. The longer it stands, the more it's worth — and the more famous it gets on the raid board.

LEVEL 03 · DUEL

1v1 your opps in duels.

A duel is a contest built for two. Same problem set, same clock — when the timer hits zero, the higher score takes the rating. No luck, no excuses.
