Rule highlights
Setup, play, winning, and house rules
Setup
- The game uses a 9×9 shogi board. Four players sit at its four edges and each set nine pieces along their own edge.
- The back rank holds silver, gold, king, gold, silver; the second rank pawn, rook, pawn; and one pawn sits in the middle of the third rank. Pieces advance towards the player sitting opposite.
- There are five kinds of piece — king, rook, gold, silver and pawn — and they move exactly as in shogi. Bishops, knights and lances are not used.
- Moves go clockwise in the order players sat down. Each time you play again, the first player moves on one seat (you can fix it in the settings).
How to play
- On your turn, move one piece on the board or drop one piece from your hand.
- Move onto an opponent's piece to capture it. Captured pieces return to their unpromoted form and join your hand; from your next turn you can drop them, facing your own way.
- Kings are never captured. A player put in check answers at once, without waiting for their turn — check jumps the queue. Play then carries on clockwise from that player, and anyone skipped does not get the turn back.
- If two or more players are in check at once, the one nearest clockwise from the player who just moved answers first.
- Rooks, silvers and pawns may promote — only when moving into, within or out of the camp of the player directly opposite you (their three nearest ranks). You cannot promote in the camps to your left or right.
- You may not place two unpromoted pawns facing your way on one file, checkmate by dropping a pawn, leave a pawn with no forward move, drop a pawn in front of a checkmated king, or leave your king in check.
Winning
- A player whose turn comes with no legal move is checkmated. Their king is turned over and stays on the board as an obstacle that nobody can move or capture.
- A checkmated player's pieces in hand and on the board go to the player who put them in check. The board pieces keep facing the way they did, and keep moving that way.
- The game ends when two players are checkmated. Survivors are ranked by players mated, then total pieces, then whose last mate came later. Total pieces includes your board pieces, pieces in hand and the fallen kings of players you mated. Equal totals on every criterion share a place. Of the two checkmated players, the one who lasted longer comes third.
- If the same position appears a fourth time, the game ends there and places are decided on points (a player giving repeated check must avoid repeating). There is no resigning.
House rules
| Name | Description | Default | Changeable |
|---|---|---|---|
| FormatFormatIn Singles all four players are enemies, and you may mate any of the other three. In Pairs the two players sitting opposite form a team, and the team loses as soon as either member is checkmated. In Pairs you may not make a move that newly puts your partner's king in check. | Play singles, where everyone is on their own, or pairs, where the two players sitting opposite team up. In pairs you may not put your partner in check with your own move, and a team loses as soon as one of its players is checkmated. | Singles | Yes |
| When the game endsWhen the game endsSingles only (Pairs ends at the first mate). "After two checkmates" is the official rule: the two survivors are ranked by how many players they mated, then by how many pieces they hold. "Last player standing" takes longer, and the last player standing is first. | In singles, end the game once two players are checkmated, or play on until only one player is left. | After two checkmates | Yes |
| A checkmated player's board piecesA checkmated player's board pieces"The mating player takes them" is the official rule: the mated player's pieces on the board become the mater's pieces, still facing the same way. With "Nobody owns them", those pieces stay on the board and anyone may capture them into hand. Either way, the mated player's pieces in hand go to the player who gave mate. | Give them to the player who delivered the checkmate (they keep facing the same way), or leave them on the board unowned so that anyone may capture them. | The mating player takes them | Yes |
| Move limitMove limitWhen the limit is reached, the game ends with a judgement. In Singles, surviving players are ranked by how many players they mated, then by how many pieces they hold (board and hand); mated players rank below the survivors. In Pairs the game already ends when anyone is mated, so reaching the limit is a draw with no ranking. | When all four players' moves together reach this number, the game ends. In Singles, places are decided by players mated and pieces held; in Pairs nobody has been mated yet, so it is a draw with no ranking. | None | Yes |
| Show legal moves | Mark the squares a selected piece can reach. | On | Yes |
| Rotate the first player | Each time you play again, the first player moves one seat clockwise. | On | Yes |

FAQ
How many players?
Four. If you are short of players, the CPU fills the empty seats — play alone against three CPU players.
How long does a game take?
About 25 minutes. Counting all four players' moves together, CPU games end in roughly 50 to 90 moves. There is no clock.
How is it different from shogi?
Four players share one board and move clockwise. Each has nine pieces of five kinds — king, rook, gold, silver and pawn. A player put in check answers at once, jumping the queue.
Who invented it?
It was devised in 1993 at the city office of Hirata, Shimane Prefecture, Japan (now part of Izumo).
Can I practise alone?
Yes — press Play vs CPU to play against three CPU players. The CPU has two levels, Easy and Normal.
Can I play at school or work (unblocked)?
Yes. It runs entirely in your browser, with nothing to download or install, so it works on most school and work networks that block app stores or game downloads.
