About this game

Find the symmetry, paint the blocks and discover a hidden pixel-art picture! Each puzzle consists of a grid containing dots in various places. The object is to reveal a hidden picture by drawing a block around each dot according to the rules.‎

Sym-a-Pix are exciting logic puzzles that form whimsical pixel-art pictures when solved. Challenging, deductive and artistic, this original Japanese invention offers the ultimate mix of logic, art and fun while providing solvers with many hours of mentally stimulating entertainment.

The game features a unique fingertip cursor which enables playing large puzzle grids with ease and precision: to draw a wall, move cursor to the desired location and tap anywhere on the screen. To draw multiple walls, press and hold fingertip until the wall is drawn and start dragging to neighboring walls.

To help see the puzzle progress, graphic previews in the puzzle list show the progress of all puzzles in a volume as they are being solved. A Gallery view option provides these previews in a larger format.

For more fun, Sym-a-Pix includes a Weekly Bonus section providing an extra free puzzle each week.

Even though, Sym-a-Pix is my favorite of the conceptis games. I have to give a 1 star for the mobile app because the cursor is the worst control system for playing. I was expecting the controls to just be tapping like everyother game in your library. In fact, I downloaded Slitherlinks just to see if that had the cursor. Nope, that game you can just tap and you get the expected lines and x's. So why can't the Slitherlinks controls be applied to this game?

The reason Sym-a-Pix controls are designed this way is to enable playing very large puzzles. We are looking into this issue, and will probably release an update with direct-touch controls later on.

Reviews from 2020 and longer ago mention the horrible cursor control, but developer replies indicated a possible future update - that did not happen. And yes, the controls are horrible, so I uninstall after about two minutes. Very disappointing, because I like these types of puzzles a lot (and would absolutely have paid for extra content in a usable app).

Really fun game, the controls drive me insane though. Why not just do like, a double tap for a solid line? Having to move the cursor is really annoying and it keeps erasing the line when i try to move it. Please fix it.

I'm afraid your question isn't clear. What do you mean by "double tap for a solid line"? Please send us an email to support@conceptispuzzles with more explanations so we can look into this suggestion
