Play Together, Compete Head-to-Head

Create a lobby, share the code, and everyone plays the same board at the same time.

Create or Join

One code, instant lobby

Create a private lobby and share a 6-character code with friends. Pick casual or hardcore mode, choose a difficulty, and you're ready. Works in both FreeCell and Minesweeper.

Group play lobby with players listed and Start Round button

Synchronized Start

3... 2... 1... Go

Everyone sees the same countdown. Same seed, same difficulty, same starting moment. No advantages — pure skill comparison. A session leaderboard tracks results across rounds.

Your Records Are Never Safe

Set a record, and someone will come for it. You'll know when they do.

The Challenge

Someone targets your record

When another player challenges your seed, you get notified. If they beat you, you see exactly how — metrics, head-to-head record, and the option to reclaim or escalate.

The Outcome

Dethroned — or defended

Every dethronement shows a full metrics comparison: efficiency, moves, time, 3BV/s. Reclaim your record on the same seed, or escalate to a new battlefield. The rivalry tracks your head-to-head history.
