About the game
The shell challenge: click the shell shown at the top right as fast as possible. A game of speed and a sharp eye for short breaks.
Shell Challenge belongs to the Puzzle mix variant in the Puzzles world and joined the catalogue on January 4, 2016. The rules, levels and on-screen language are set by the game’s creator, and a short guide appears on its start screen.
How to play
- Read the game’s rule on the start screen.
- Make the move that opens up the most options.
- Solve the level and move on to the next, harder one.
Tips for a better game
- The first levels teach the rules, so play them slowly and watch what each move changes.
- In puzzles with a single solution, start where you have the fewest options.
- If you get stuck, restart: a fresh look often spots the way at once.
