This game at its core is incredible! It is a very unique puzzler that hurts my brain; just what I’m looking for in a game. It is terribly unfortunate how the token system works to play levels. You have to use a token to play each level, but the only way to get the tokens(after the first chapter) is to play the daily puzzle. These puzzles are extremely addicting and I don’t want to wait. I understand the dev needs to make money, but I would love to see the tokens accrue to a certain number after a certain amount of time like many games “life” system. Additionally, the “my sets” section boasts that you can play as many as you want once collected, but yet, you have to use tokens to unlock them AND to play them. Once you use tokens to unlock the set, they should be free to play. All said, I would pay a pretty penny for a premium version with no tokens and/or no ads. I know the game is in early dev, but would hate to see it fall apart from such an integral and difficult play mechanic. P.S. if you are going to have ads, I should be able to watch an ad for tokens.

Many puzzles have multiple solutions, but only one “correct” solution. I gave up pretty quickly after many puzzles just became a guessing game of which solution was the real one.

I absolutely love the basis of this game which is why I gave it 5 stars! It is challenging but not so hard that you can’t solve it and this really tickles both the pattern recognition part of my brain with my love of great graphics. I love trying to figure out the rules and patterns. That being said, the only way to play is by spending tokens that you only get a few each day by playing the daily game. I do really wish the mechanism had something like other games where you earned a token every 5 minutes until you had 5 in your bank or something. It would absolutely make things more playable. But such a great gameplay!!!

While I enjoy this game and how accessible (and fun) it makes set theory, it does not always accept valid answers. In one case, the puzzle was symmetric and would accept one solution, but not its inverse.Ex:The game acceptedS1 = {a,b,c,d}S2 = {c,d,e,f}S3 = {b,d,f}BUT would NOT accept the sets inverse whereS1* = {a,b,c,d}S2* = {c,d,e,f}S3* =-(S3)= {a,c,e}In this case, there were NO other shapes left over. It is disappointing that the game overlooked some inverse or negated solutions, especially after other reviews have been pointing out similar issues. I am unable to upload screenshots, but am willing to email them. The level that I first noticed this was the 23rd on the trail in zone 2.
