DotFlow - Simple Brain Puzzle
Connect dots, fill the grid
Free · Designed for iPad. Not verified for macOS.
A free color-flow puzzle: connect matching dots and fill every cell. Train your brain with logic, paths, and a little patience. Perfect as a casual game for a commute, a short break, or a quiet evening.
DotFlow is a connect-the-dots logic puzzle. Draw pipes between pairs of the same color. Lines move only up, down, left, or right. They cannot cross. You clear a stage only when every cell is filled—so linking pairs is not enough. You have to plan the routes.
Easy to learn, harder as colors and grid size grow. The app includes 55 original stages from 5×5 to 8×8, plus a daily 3–5 color challenge generated on your device. No account. Start playing immediately.
Who it’s for
• Anyone looking for a free puzzle game
• Fans of flow puzzles, pipe puzzles, and Numberlink-style fill-the-grid challenges
• People who want a short brain teaser or mind workout
• Anyone who wants a focused, relaxing way to pass a few minutes
How to play
1. Connect each pair of matching colored dots with a line
2. Orthogonal moves only—no diagonals, no crossing
3. Fill every cell to clear the stage
4. Undo or restart if you get stuck. Hints unlock after a short rewarded ad
What’s inside
• 55 handcrafted stages with a gradual difficulty ramp
• A daily challenge seeded by the date on your device (same day, same board)
• Undo, restart, and optional hints
• Progress and settings stored on the device
• BGM, sound effects, and haptics can be turned off
The daily puzzle is not a multiplayer mode. It is generated locally from the calendar date, so you can think at your own pace. The puzzle itself can be played without an account. Loading ads still needs a network connection.
Free to play
The app is free and supported by ads: a banner, an interstitial after some clears, and a rewarded video for hints. There are no in-app purchases. If an ad fails to load, the game continues.
Tips
Start along the walls, lock in pairs with fewer colors first, and close dead ends early. Use undo to test a line. Save hints for last so the logic still feels like yours.
