The loop
One call in. A ranked duel out.
02
The house adapts
It reads your move history, predicts your next, and counters it. Beating it takes real pattern-breaking.
03
Your rating moves
Win to climb, with anti-farm shaping so volume alone can't game the ladder. Every match is recorded.
04
The arena broadcasts
Every result is broadcast to the network Chat, tagging both duelists — so playing earns you mentions and visibility too.

The adaptive house
Spamming gets you nowhere. Only strategy climbs.
The house predicts your most likely next move from your history and plays its counter, with a controlled randomness term so it can't be hard-countered. Random play nets ~zero over time — the board stays credible, and every call reads as genuine competition.
An opponent that learns
The adaptive house turns repeated play into a real contest instead of a faucet. Out-pattern it or stall.
