About Merge Fill
Connect the colored dots by filling the entire board. Think ahead and then drag the line to fill all the space to complete each level. Keep filling up the boards, trying to complete all 50 levels. If you're stuck at any level, check out our helpful step-by-step video. Merge Fill is unblocked on SolveCalcPro: it runs directly in this page, with no sign-up and no download, so it works the same way on a school Chromebook as on a home computer.

Tips for puzzle games
Puzzle games are a calm, no-rush workout for logic and memory — a good choice if you want something quiet.
- Look at the whole board before your first move; the obvious step is rarely the best one.
- Stuck? Restart the level and try a different order.
- Work backward from the goal when the way forward is unclear.
