Periodic Table Grid Memory Game

The Periodic Table grid memory game features chemical element pictures - each tile shows an element symbol and its distinctive color coding. You don't need any chemistry knowledge to play: the challenge is purely visual, memorizing where each tile sits on the grid.

This is a grid memory game, not a classic card-flipping game. Instead of finding matching pairs, you must remember the exact position of every element across the entire grid - a particularly challenging workout because many element tiles look similar at a glance, requiring careful attention to detail.

The game is free to play in your browser with no download and no sign-up. Works on phone, tablet, and desktop.

1. Press Play - The chemical element pictures appear on the grid.
2. Memorize - Study the grid and remember where each element sits. You have a set display time before they disappear.
3. Drag them back - When the time runs out, the grid goes empty. The pictures appear below in a random order. Drag each one to the cell where you think it was.
4. See your score - When you place the last picture, your score appears automatically - for example 8/8 correct.
5. Adjust difficulty - Use Level to pick a bigger grid (up to 5x4 with 20 pictures). Use Display time to reduce how long you have to memorize. Use Countdown to show or hide the timer.
