On your turn, draw a tile and discard one. Build four groups and a pair: a group is three consecutive numbers of the same suit, three identical tiles, or a declared Kong of four identical tiles.
Chi takes a discard to make a sequence; Peng makes a triplet; Gang makes a Kong; Hu declares a winning hand. Only legal actions appear. Concealed Gang uses four matching tiles in your own hand; it does not take the previous discard. You may discard instead. Double-click a tile to discard; press Up Arrow to Pass when a claim is offered. After you discard or Pass, the next AI action happens automatically after a short pause. AI finishes its follow-up action after Peng, Chi or Gang automatically. For later AI turns, press Proceed or Left Arrow. After Leo discards, the game always waits for you: claim or Pass, or press Proceed / Space / Left Arrow when no claim is available to draw and begin your turn.

How to play
Fill squares to reveal a picture. The numbers beside each row and above each column describe its filled groups, in order. For example, 1 2 means one filled square, at least one empty square, then two filled squares. A 0 means the whole line is empty.
Use Fill for picture cells, Cross (×) for known empty cells, and Erase to clear a mark. Tap or drag to paint. Tapping an existing Fill or Cross clears it. Each drag paints one value throughout; Undo reverses the entire stroke. On a laptop, right-click also places a cross.
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.

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.
Matching pieces clear, the pieces above fall, and new pieces enter from the top. New matches trigger cascades. Clear pieces are worth 10 points each, multiplied by the cascade number within that move. Intersecting matches count each piece once.
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.
Match four in a straight line to leave a striped piece. A horizontal match creates a row-clearing stripe; a vertical match creates a column-clearing stripe. Match five or more in a straight line to leave a rainbow piece instead. Swap a rainbow with any neighbor to clear every piece of that type. Swapping two rainbows clears the board. A stripe blast activates other stripes; if it hits a rainbow, that rainbow clears the most common type. Only removed pieces score points. Earlier saved rounds keep their original rules; choose New board to play with rainbows.
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.
Keyboard: Tab to the board, use arrow keys to move, and Enter or Space to select each neighboring piece. Escape clears selection. Your board and personal records stay saved in this browser.

You found every word.
How to play
Find every listed word in the letter grid. Swipe from its first letter to its last, or tap the two endpoints. You can select a word in either direction.
Easy uses words placed across and down. Standard and Challenge also include diagonal and backward words. Each word follows a straight line; words may share letters. Found words stay marked in the grid and crossed off the list.
Hint marks the first letter of an unfound word. Using it marks this puzzle as assisted in My Progress. There is no timer or penalty for a wrong selection.
Daily puzzle: everyone gets the same 10 × 10 board for a date, with a rotating theme. A new puzzle arrives at midnight UTC. Daily, regular and shared-puzzle progress are saved separately on this device. Share copies a link to any puzzle without the answers; close the link with Close or Escape.

You cleared every tile.
How to play
Tap two identical free tiles to remove them. A tile is free when nothing covers it and at least one of its left or right sides is open. Brighter tiles are free; shaded tiles are blocked.
Clear all tiles to win. This is a solo matching puzzle. You do not need to know the rules of four-player Mahjong.
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.
Draw one card, or select a card and tap its destination.
How to play
Tap the stock to draw one card. When it is empty, tap it again to recycle the waste. You have unlimited passes and no timer.
Build the seven columns downward in alternating colors: a red 7 goes on a black 8. Move a face-up card or a complete descending stack. Only a King can fill an empty column. Uncovering a face-down card turns it over automatically.
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.
Swipe the board or use the arrow keys.
How to play
Swipe in any direction, use your keyboard’s arrow keys, or tap the arrow buttons. All tiles slide together. Matching numbers combine into one tile: 2 + 2 makes 4, then 4 + 4 makes 8.
Each slide that changes the board adds a new 2 or 4 tile. A tile can merge once per slide. Your score increases by the value of each merged tile.
Reach 2048 to win, then keep playing if you like. The round ends when the full board has no matching neighbors. No timer or registration. Your board and personal best are saved on this device.
Choose a piece, then tap its top-left position on the board.
How to play and score
Tap a piece, then tap the board where its top-left corner should go. You can also drag a piece onto the board. A preview shows whether it fits. Pieces keep their orientation.
Fill any row or column to clear it. Use all three pieces to receive a fresh set. Play ends when none of the remaining pieces fits. There is no timer.
Each block placed earns 1 point. Each cleared row or column earns 10 points, plus 5 extra for each additional line cleared in the same move. Best scores and the current game save on this device.
Keyboard: Tab to choose a piece or enter the board. Use arrow keys to move between cells and Enter or Space to place. Escape clears your selection.
Color Sort Challenge
Plan your moves around matching colors and two buffers.
Move a top group of matching balls into an empty lane or onto the same color, with enough space for the group. Two empty buffer lanes help you plan. Complete the puzzle by collecting each color in its own lane.
Choose a board from 5 × 5 to 11 × 11. Play Solo, challenge Marcus on the same puzzle, or watch two AI opponents find their routes. Undo lets you reconsider a move; there is no countdown timer.
For example, a red top group can go into an empty buffer or onto red, but it cannot go onto blue. A transfer moves the maximum matching top group that fits. Opening a lane can be useful, but filling both buffers too early may leave you with few legal choices.
Try uncovering a buried color while keeping at least one useful destination available. Finishing a single-color lane can simplify the remaining board, but compare the next move before using your last buffer. Restart returns to the initial arrangement. Share Puzzle lets another player try the same starting board without revealing your route; local progress remains separate.
