Free puzzle and logic games

Merge 2048 — Slide the tiles, merge the numbers, reach 2048.

Merge 2048 is the number puzzle where every move slides the whole board. Two equal tiles that collide become one doubled tile — keep merging until you build a 2048.

• Swipe, drag, or use the arrow keys to slide every tile in one direction.
• Tiles with the same number merge into one tile worth double.
• After every move a new 2 or 4 appears in a free square.
• Reach 2048 to win — then keep going for a bigger tile.

• Pick one corner and keep your biggest tile parked there for the whole game.
• Avoid sliding in the direction that pulls your largest tile out of its corner.
• Keep the board in two tidy rows: fill one row completely before starting the next.

Minesweeper — Clear the field with logic alone. One wrong tap and it is over.

Minesweeper is the classic deduction puzzle. Every number tells you how many mines touch that square — read the numbers, mark the mines with flags, and open every safe square.

• Tap any square to start. The first tap is always safe.
• A number shows how many mines touch that square, counting all eight neighbours.
• Long-press or right-click to plant a flag where you are sure a mine is.
• Open every square that is not a mine to clear the board.

• Start in a corner: fewer neighbours means less to work out.
• When a number already has that many flags around it, every remaining neighbour is safe — tap them all.
• Use the flag button to switch your tap into a flag, which is easier than long-pressing on a phone.

Sudoku — Every digit once per row, column and box. Pure logic, no guessing.

Sudoku is the number-placement puzzle with a single rule: each row, each column and each 3×3 box must contain the digits 1 to 9 exactly once. Every puzzle here is generated with exactly one solution.

• Tap a square, then tap a number to place it. Tap the same number again to take it back.
• Every row, column and 3×3 box must hold the digits 1 to 9 with no repeats.
• Turn on Notes to pencil in candidates when you are not sure yet.
• Fill all 81 squares correctly to finish the puzzle.

• Start with the digit that already appears most often — it usually has the fewest empty squares left.
• When two candidates can only fit in the same two squares of a box, no other square in that box can take them.
• Highlighted rows, columns and box make it easy to spot what a square is missing — use the number keys for speed.

Mahjong Snake — Steer the tile snake, swallow every tile, chase the golden one.

Mahjong Snake is the classic snake game rebuilt with mahjong tiles. Steer a snake made of tiles around the board, swallow every tile it meets, and catch the fleeting golden tile for a big bonus.

• The snake crawls forward on its own. Steer it with the arrow keys, WASD, or by swiping.
• Swallow the tile in your path to score ten points and grow one tile longer.
• Now and then a golden-framed tile appears. It is worth forty points, but it only stays on the board for six seconds.
• Hitting the wall or your own tail ends the run — and the snake speeds up every three tiles, so late runs are tight.
• Press Space, or the Pause button, whenever you need a breath. Your best score is saved in your browser.

• Turn early. Late turns near a wall are how most runs end.
• Curl along the edges to keep the middle open — a long snake needs room to loop.
• Chase the golden tile only when your tail is short or the path to it is a straight line.
• The pace rises every three tiles. Around tile twelve, start planning two moves ahead.
• Quick double taps register as a queue, so you can bank the next turn while the snake is still crawling.

Mahjong Bubbles — Aim, shoot, and pop groups of three before the wall reaches the bottom.

Mahjong Bubbles is a bubble shooter played with mahjong tiles. Fire tiles at a hanging wall, match three or more of the same face to clear them, and drop everything left dangling. A new row pushes down every few shots, so keep the wall thin.

• Aim with the mouse or your finger. The dotted guide shows exactly where the tile will fly.
• Tap or click to shoot. The tile sticks where it lands — against the wall, against another tile, or on the ceiling.
• Three or more tiles of the same face touching each other vanish. Anything left floating with no path to the ceiling falls as well.
• Every six shots a fresh row grows along the top and pushes the whole wall one step closer to the bottom.
• If the wall crosses the dashed line above your cannon, the run is over. Clear the entire wall to win.
• Press Space, or the Pause button, whenever you want to stop and study the wall. Your best score is saved in your browser.

• Aim at the lowest, most isolated clusters first — they are the ones that trigger big falls.
• Cut the wall's supports. Clearing a thin column can drop an entire wing of tiles worth far more than the three you matched.
• Watch the preview tile next to the cannon. Plan your shot around it before it becomes your current tile.
• Bounce off a side wall to reach a pocket that is blocked from below.
• When the wall gets within two rows of the line, stop chasing points and clear the bottom row instead.
• Colours matter more than position. Scanning for triples before you shoot beats aiming at whatever is nearest.
