Fissle

Fissle (formerly Flux Grid) is a daily word puzzle where you trace hidden words across a 4×4 grid to clear every tile before your fuel runs out.

Connect adjacent letters to form valid words and remove them from the board. The challenge is not just finding words, but finding an efficient path through the grid. Your final performance is rated from 1 to 5 stars based on how efficiently you solve it.

• Trace adjacent letters across the grid to form words.
• Each valid word clears its tiles from the board.
• Clear the entire 4×4 grid before you run out of fuel.
• Earn 1 to 5 stars based on your efficiency.
• Take on a tougher themed 5×5 puzzle where accepted words fit the day's theme.
• Race another player head-to-head in 1v1 mode.
• Try Speed Streak for a faster-paced variation.
• Browse the full puzzle archive when one daily grid isn't enough.
• Play on the web or through the native iOS and Android apps.

Why we like it:

• ✅Finding words is only half the puzzle. Clearing the grid efficiently adds a satisfying strategic layer.
• ✅The 4×4 daily and themed 5×5 offer two notably different challenges.
• ✅Race mode, Speed Streak, and the archive give you plenty to do beyond the daily puzzle.

Hint: Think beyond the first valid word you spot. A slightly longer or better-positioned word can leave the remaining letters much easier to clear and help you earn more stars.
