Ways to play

- CUSTOM ROOM

Custom rooms

Create a room and share its code or invitation link. Up to four players can play together, with additional seats for spectators.

- AI BATTLE

AI battles

Practice white-edge connections, closing regions and assessing risk against computer opponents. The game offers different AI options.

- RANKED

Ranked matches

Use matchmaking to compete for seasonal standings. RTG changes depend on results and your opponent's rating.

- KNOCKOUT

Knockout tournaments

Follow a tournament bracket and advance round by round. This is a separate format from Ranked rating-based matchmaking.

- MATCH FORMAT

One round or three?

Mode	Rounds	Result
Ranked	1	The round's result decides the match.
Regular / AI	3	Decided by the total score across three rounds; a two-player score tie may end in a draw.
Knockout	3	Total score, then round wins, then a tile draw if both remain tied.

A single-round match uses the same placement and closure-scoring rules. The difference is when the match result is decided.

Three-round totals and round-win marks

Scores earned in each round accumulate into the match total. Winning two rounds does not automatically win the match. The small round-win marks next to a player's name record how many rounds that player has won.

In knockout matches, the player with the higher score in a round earns 1 round win. If that round is tied, neither player earns a round win. Round wins are the second criterion when the match totals are equal.

How is knockout advancement decided after three rounds?

Compare the total score across all three rounds: The higher total advances, even if that player has fewer round wins.
If totals are equal, compare round wins: The player who won more rounds advances. For example, at 30 points each, 2 round wins beat 1 round win.
If both totals and round wins are equal, draw tiles again: Each player selects a different tile from four concealed choices containing 1, 2, 3 and 4 white edges. After the reveal, the player with more white edges advances. The system selects automatically for a player who does not choose before the deadline.

The draw only decides knockout advancement: There is no fourth scoring round, and the scores already earned remain unchanged. Regular two-player / AI matches allow a score tie and do not use this advancement draw. An equal-score single-round Ranked match can also end in a draw.

ROUND shows the current round. This example is a regular three-round match.

- RATING

Ranked & RTG

Ranked uses an Elo rating system. A new account starts at 1200 RTG. The first 10 matches are a placement period, during which rating changes may be larger. Ratings continue to adjust afterward based on both players' ratings and match results.
