Pixel Pairs and Three in a Row let you think between moves. Pixel Pairs is a solo memory puzzle: reveal two tiles, remember their positions, and find eight pairs. Three in a Row is a local two-player strategy puzzle on a nine-square board.
Neither game needs rapid steering. Both use ordinary HTML buttons that you can select with a mouse, touch, or keyboard. Pick Pixel Pairs for a solo session or Three in a Row when someone can share your screen. The second player is local, not an online opponent.
For more solo puzzles, merge numbers toward 2048, uncover safe squares in Minefield, turn off a grid in Lights Out, or put Slide Fifteen into order. Four in a Row is another option for two players sharing one screen. Every game has a playable page and a matching source download.
Turn over two tiles at a time and find all eight matching pairs.
Controls: Select two tiles with your mouse, touch, or keyboard. Match all eight pairs.
Tip: Use a regular scanning order. Remember both positions after a mismatch instead of immediately guessing again.
A two-player game of tic-tac-toe, played on the same device.
Controls: Two players take turns selecting an empty square. Make a line of three to win.
Tip: Check for an immediate win or a blocking move before choosing a square that builds a future line.
Slide matching numbers together. Build a 2048 tile before the board fills up.
Controls: Use arrow keys, swipe the board, or select a direction button. Equal tiles merge once per move.
Tip: Keep the largest tile in a corner and leave room to combine smaller pairs.
Find the safe squares on an 8 × 8 board. Read the numbers and flag ten hidden mines.
Controls: Select a square to reveal it. Right-click to flag, or enable Flag mode before tapping. Reveal all 54 safe squares to win.
Tip: Use the neighboring numbers. Flag a suspected mine before opening nearby squares.
Drop discs into seven columns. Connect four before your opponent does, on the same device.
Controls: Two players share one device. Select a column button to drop a disc. Connect four horizontally, vertically, or diagonally.
Tip: Watch for immediate threats in every direction, including diagonals.
Turn off all 25 lights. Each tap flips one light and its immediate neighbors.
Controls: Tap a light to toggle it and its up, down, left, and right neighbors. Turn every light off to finish.
Tip: Work from the top row down. Repeating the same press twice cancels its effect.
Put fifteen numbered tiles in order by sliding them into the empty square.
Controls: Select a tile next to the gap to slide it. Arrow keys move the empty square. Arrange 1–15 left to right, with the gap last.
Tip: Finish the top row, then solve within the remaining area without disturbing it.
In Pixel Pairs, the hidden board is the challenge. A mismatch leaves both tiles visible briefly before they turn over again. In Three in a Row, every move remains visible; the challenge is anticipating another player. A full board can be a draw, so the result depends on both players’ decisions rather than simply finding all the pieces. Merge Tiles teaches directional transforms, Minefield uses neighbor counts and flood fill, Lights Out uses reversible toggles, and Slide Fifteen demonstrates solvable shuffling. Four in a Row adds gravity and directional line scans.
Yes. The button boards use buttons that support mouse or touch input. Keyboard users can move focus between tiles and activate them.
No. Three in a Row needs two people on the same device. Pixel Pairs is designed for one player.
