Showdown · 1v1
Two operators. One gate.
A duel fought the old way. Invite an operator, spawn the same challenge at the same second, and the first valid submission takes the gate. No flag to paste: a submitter binary inside your own instance calls the win home.
The rules
How a duel is fought.
Short, fair and the same for both sides.
- The invite
- Challenge any operator. Whoever accepts picks the ground.
- The ground
- The accepter chooses the category, from five, and the round length, from 30 to 90 minutes.
- The challenge
- Arena serves one neither of you has opened before. You both spawn it at the same second.
- The win
- The first valid submission ends it. A submitter binary inside your own instance calls the win home, so there is no flag to paste or share.
- A clean clock
- If time runs out with no winner, sudden death drops in: an easier variant, half the timer, 0.7x the rating swing.
- Rating
- Standard ELO at K=32. Beating someone above you pays out hard. A draw costs both sides five points.
