Rules and controls

Keyboard controls

Peng / Gang / Chi / Hu (Win), when legal. Multiple choices use arrow keys and Enter, or a click.

H

Show a hint. All actions are also available through the buttons.

When another button is focused, Enter and Space keep its normal button action. During a Chi/Gang choice, all four arrow keys select an option and Enter confirms it.

Concealed Gang uses four matching tiles in your own hand; it does not take the previous discard. You may discard instead. Only legal actions appear.

After Leo discards, claim or Pass if offered. Otherwise choose Proceed, Space or Left Arrow to draw and begin your turn. Hint, Controls and New session are below your hand.

Tap an opponent to inspect exposed groups; concealed tiles show only their count. Hover, focus or select your tile to read its name. Click the selected tile again to deselect it. The Controls button reopens the guide. A steady gold outline marks the latest player to act; claimed discards leave the table.

Green clues have their filled groups in place. Red clues cannot fit your current marks; reconsider that line. Hints outline a deduction from the clues or identify an incorrect mark, and count as assistance in My Progress.

Every puzzle has one verified solution and can be solved by row-and-column deductions without guessing. You win when all picture squares are filled correctly; crosses on other squares are optional. The picture’s name is revealed at completion.

There is no timer or mistake penalty. Keyboard: arrow keys move around the grid; Enter or Space applies the selected tool. Escape cancels a stroke or hint. Your puzzle, undo history and completed records are saved in this browser.

Daily puzzle: everyone gets the same picture for a UTC date, alternating 5 × 5 and 10 × 10. A new puzzle arrives at midnight UTC; tap Daily puzzle to open it. Daily and practice marks are saved separately on this device. Share puzzle copies a link without revealing the picture or its answer. No account or streak is required.

How to play

Swap two neighboring pieces to form a horizontal or vertical line of three or more identical pieces. Swipe a piece toward its neighbor, or tap both pieces. Diagonal swaps do not count.

Reach the score goal before you run out of moves. Only valid swaps cost a move; a rainbow swap also uses one move. Boards with no legal swaps refresh automatically at no move cost. There is no timer, lives system or waiting period.

Choose Shapes, Fruit, Flowers or Numbers in Pieces to change the look without changing your round. Your choice is remembered in this browser.

Each new round chooses four to seven pieces from a larger collection, depending on difficulty. Your selection stays the same when you resume or retry this board. Changing Pieces only changes its appearance.

Choose Beginner (7×7, 4 types), Easy (8×8, 5), Normal (8×8, 6), Hard (8×8, 7) or Expert (9×9, 7). Hint outlines a legal swap and marks this round as assisted. A hint suggests a move, not a guaranteed win. Retry starts the same board again; New board deals a different one.

How to play

Each new deal has a verified solution, but choosing a different pairing can block progress. Undo reverses the last match or reshuffle. Hint outlines an available pair; it does not promise a full solution.

Reshuffle rearranges remaining tiles with a verified solution when their positions allow it. If the remaining stack cannot be cleared, undo a pair first. Hint or reshuffle marks this deal as assisted in My Progress. Undo does not remove that mark.

There is no timer. Your deal and wins are saved in this browser. Keyboard: Tab and Enter select tiles; Escape clears your selection. Hover or focus a tile to read its name.

Daily deal: everyone starts with the same verified arrangement for a UTC date. Garden, Terrace and Bridge rotate each day. Tap Daily deal for the new board after midnight UTC; open boards stay in place. Daily, regular and shared-deal progress are saved separately. Share copies a link to any starting arrangement, without your moves or the solution. Close the link with Close or Escape. No account or streak is required.

How to play

Build the four foundations from Ace to King, each in its own suit. A single card from a foundation may move back to a column if needed.

Tap a card, then tap its destination, or drag a card or stack. Keyboard: use Tab and Enter to select cards and destinations; Escape clears your selection. Undo reverses the last action, including draws and recycling.

Hints suggest a possible move, not a guaranteed solution. Auto-finish becomes available when stock and waste are empty and all remaining cards are face up. Hint or auto-finish marks that deal as assisted in My Progress. Not every shuffled deal can be won.

Your deal and wins stay saved in this browser on this device. No registration needed.

How to play
