My new favorite game! It's perfectly challenging: you will not find the solutions to all variations without learning new concepts. I'm not using the web to help me and yet as I try new puzzles I can apply new techniques to the previous problem. Very well designed, pleasant to interact with but also stimulating on an intellectual level. Plus my boyfriend likes it too :)
Great game all round if you are interested in mathematics, patterns, or problem solving. Totally worth spending some spare change ($1) for all the packs, and even if you pay it doesn't get any less challenging. Fun enough for a 10-11 year old to complete, but still hard enough for an adult to spend an hour on a problem. Gameplay is smooth, without bugs, and logical. Seriously recommend spending some change to support the developer. 10/10
Really love playing using this app. It's not only extremely fun and challenging but it has also taught me a few things as well. I just have one suggestion for the developers of this wonderful app, why don't you make a mode separate to the puzzles that allows the user to just create geometric structures on there own. Sometimes I get stuck on a puzzle and just want to experiment with different shapes to see how they look. Just an idea but other than that love the game.
I wish it would state the axioms and theorems you're using and developing along the way - would help with remembering substeps you need for more complicated problems. I also wish you could access your solutions to earlier questions without losing progress on your current problem, for pretty much the same reason. Otherwise, well done and controls only get finicky sometimes and within reason.
This starts off being a lot of fun. The interface is very usable. I've learned a lot of things about constructions. They never taught us about collapsible compasses when I was in school. That adds a level of interest because a lot of the tricks I learned in 6th grade don't work. After working through this for a while my opinion of it has dropped some. It's a lot of fun at first, but you eventually reach the point where you're completely stuck. Stuck in the sense that you will never figure it out on your own. You have to know some arcane fact in order to solve it. Sometimes I've been able to work out a solution with sufficient off-line calculation; sometimes solution becomes either a web search for that arcane fact. Still, worth downloading, and worth paying for.
Brilliant game, I haven't seen anything like it in the Play Store. It challenges your brain in ways that school doesn't, and it feels very rewarding finding the solution
