Seriously? Fun until you walk away from the game. Was at level 27 then checked email and came back only to have it reset to level 1. LAME! no option to select your level or anything.
Poor level design Sometimes some level are not makeable. You have to relaunch the level until you find some thing that can work
I've played better. For example a game called "Entangled" is much better and more relaxing. The graphics on this are so bad it drives my brain nuts.
Nice game, if sometimes a bit fiddly. Would like to switch off neon effect, and to pause before going to next level
Decent but boring good concept... The difficulty goes up VERY gradually, so after the first few you've got the hang of it, then it starts to get boring for a while until the harder levels, and even easy levels take 10 min to finish. Would add another star if you could skip ahead levels. ... app asks internet permission but no ads, weird. and can't move to SD. on my tiny phone screen level 50+ too small to do without a stylus. Helps to leave 1 corner undone on purpose until the end so you can see the completed level.
Its a good game but after completing level it just jumps 2 next level without pausing so u can see the final puzzle needs option 2 go 2 next level.
Place, group, and erase the numbers. Enjoy a innovative number puzzle game!
