Periodic Path
How to play
- 1Two elements are shown on a periodic table with the rest hidden. Connect them.
- 2Type any element and place it. It appears in its real place. A path runs up, down, left and right, never diagonally.
- 3No guess limit. Stuck? The bulb turns over a hidden square and places its element for you (a few per day), and the flag gives up.

About Periodic Path
Periodic Path is a free daily periodic table game. Every day you get two elements and a periodic table with every other element hidden. Type element names or symbols to reveal the elements between them, one step at a time, until the two ends join. Everyone gets the same puzzle, and a new one arrives at midnight.
Tiles are coloured by element family, as on a classroom periodic table. The bottom two rows, the lanthanides and actinides, belong inside periods 6 and 7: barium leads into lanthanum, lutetium leads out to hafnium, radium leads into actinium and lawrencium leads out to rutherfordium.
