rond défi

"Fun offline game with increasingly complex puzzles. Only complaint is that I wish it had more levels."

"simply addicting"

"Simply put, a purely mathematical game. I'm a chemist & yes, the first thing I thought of when playing were the nature of chemical bonds. Lovely for those into science/math, otherwise one could get a bit bored quite easily compared to all of the other high percentages of 'high activity, lots of color in your face' kind of apps."

"was working fine before orea, now no longer works properly"

"Clever. It's a pretty neat concept, one I haven't seen before. The controls are simple and easy to use. The visuals are pretty good - what visuals there are. It's mostly numbers in circles and white lines."

"It's a new and very interesting way to train the brain with numbers and operations. The bond system inspired by chemistry makes everything very enjoyable."

"Nice game. I think the balls should be a lil bigger underneath."

"Just managed to cut down on my Sudoko addiction and this happens."

"Simple, elegant, and lots of fun. Now, if they wanted to make it really REALLY challenging, then, instead of simply telling you the numbers, they could instead give you the possibilities as actual chemical elements (e.g. nitrogen, oxygen, helium, & carbon). Nonetheless, this setup is awesome. I'd be willing to pay for really advanced levels. Very well-made game!"

"Brilliant game! Thanks for the excellent gaming experience! I really love hiBret puzzles!"
