Dot Art: Picture Puzzle

Copy the picture dot by dot on a magnetic pegboard.

Free to start · All ages · PEGI 3 · Android

A picture sits on the card above the board. Copy it, one coloured dot at a time, until the board matches it exactly. Tap a colour to load it, or drag a dot straight out of the tray — either way it snaps into the nearest hole and stays put. No timers, no lives, no pressure: it is made for anyone who finds that sort of thing quietly satisfying, grown-ups included.

  • Lots of pictures, plenty of themesSky & garden, food, pets, wild animals, under the sea, faces and more. The first few themes are free; unlock the rest one at a time or all at once, with a one-off purchase.
  • A new picture every dayA hand-drawn picture of the day you won't find on the shelf. Solve it to grow your streak — and one missed day needn't end the run.
  • Boards to grow intoEasy, medium and hard, each bigger than the last.
  • Nudges, not naggingA hint points at the next missing dot when someone gets stuck.
  • Draw your ownFree-play boards up to 12×12, with mirror mode and save. Send a drawing as a picture, or as a challenge a friend can copy in the app.
  • Go for the gold starSolve it with no dots wasted. Dark mode, too, for the evening wind-down.

About LudwigTech

LudwigTech is one person: Byron, a software engineer who started building apps for his own kids and kept going — sometimes for them, sometimes for himself. Every picture, price and sound effect has been play-tested by a fairly demanding focus group at the kitchen table.

There is no team, no investors and no growth targets — just apps I am happy to hand my own children, and one I play myself. If you download one, that genuinely helps: it is what keeps the next one getting built.

Want to help? Installing an app, leaving a review on Google Play, or passing it on to someone who would enjoy it all make a real difference.
