4 ★ Works well, and a neat tool for practicing arithmetic...however, as a game, it's kind of boring and repetitive. I mean, I love math, so it keeps me engaged, but it's frustrating that the puzzles all break down to a fairly small number of solution patterns. I wish there were more variety. Often, multiple puzzles in a row will require more-or-less the same simple solution (e.g. 8205, 0193, etc.), and I start to question why I have this installed. Also, I often miss when trying to insert operators.
5 ★ Excellent, fun, quick puzzle game. Each puzzle lasts a few seconds, maybe 10- 15 seconds for the really tricky ones, so that you can do them in between focusing on other tasks. Absolutely perfect game for the cell phone. One thing might need to be clarified in the instructions: you can't leave numbers alone to create multi- digit numbers, but I didn't see that explained in the instructions. So, for example, if you have 4 3 6 2, you can't make that (42/6) + 3. I got hung up on that for a while.
5 ★ I am at Level 50, and it has defintely been quite the brainteaser for me. Some levels were easy, and others has me staring amd swapping at it for minutes. The gameplay is quite simple but requires thought, which is a nice break from all the half-baked action games, "puzzle" games, and idle games (I know there are others but these are the most popular). I do feel there is not much replayability when you complete a level since there is only one solution per lvl. But I still definitely reccommend.
5 ★ What a fantastic game. The interface is refreshingly simple. The concept is simple as well but the problems gets progressively harder. The great thing about this game is you don't even have to have it open to enjoy it. I think about the more challenging puzzles without using my phone. Fantastic work and incredibly kind of you to not burden it with advertising. Sincere thanks. update: I purchased the add-on. It is fantastic as well. I saw another reviewer suggest adding zero as a target. 👍
4 ★ Clean, well made and ad free. Fairly easy, though - at over 300 levels done, I can count on one hand the levels that made me think a bit, and even 3/5 into the game almost everything falls into 4 or so patterns with roughly the same solution each time. I could see this being a solid developmental tool for kids in grade school, but it's otherwise a primarily low thought level, relaxing game.
5 ★ It's a delightful mixture of simple but not mindless, although I'm only a tenth(!) of the way through the game so it's entirely possible the truly hard parts are yet to come *ed:* yes to the reply it gets way harder but in a frustrating way as one can only use _infix_ operators not the mathematical symbols as you may know them. But I guess if it was obvious it wouldn't be a game
5 ★ What a game! With a beautiful, minimalist design, crisp sounds, and a completely ad-free experience, I am blown away by the quality on display here. The puzzles are deceptively complex once operations begin to become unavailable. This has become my go-to puzzle game when I'm looking to relax or kill a few minutes. Top notch game, 11/10, 6/5, this sets the bar very high for mobile games.
4 ★ very stimulating and fun, there are hard levels and easy levels mixed throughout and randomized as to make it challenging, but rewarding at the same it. it explains the game and its functions really effectively and concise. the only down side i can see to this game is that it involves math.
4 ★ Seems like a great app for teaching kids the order of operations. I'll add this to my repertoire. It only lacks five stars because, if I'm to assign this as homework, I would strongly prefer that the app record past solutions. A nice addition would be granting am award for completing various challenges per level - can you complete this without parentheses? Can you complete this in 3 different ways? But I understand that's a lot of work. I'd REALLY like that log of past completions though.
4 ★ IF You don't like to do math problems this is a ZERO! Otherwise it's a great way to pass some time and stretch your brain (especially if you're a stoner like me). No Ads! My arthritic fingers have trouble with the UI and getting the symbols to slot. I don't know the exact term but it's like the hit box (?) is too small. otherwise having fun.
4 ★ Really solid and fun easy-going math game. My only small issue is the level scaling seems to sometimes go backwards in difficulty for several puzzles, then jumps forward again. Even later puzzles can sometimes require only very simple addition. But otherwise a really fun brain teaser and I love the commitment to an ad free game. Thanks so much to the devs!
3 ★ This game was relaxing for a while, but once I reached the too-difficult-to-be-fun puzzles (around #415 or so) I was done. All the previous puzzles had provided insufficient learning experiences for me to tackle the tougher puzzles toward the end, so then the puzzles became just pointless frustration rather than anything I could enjoy solving.
5 ★ Please never add ads. The mobile gaming industry is a blight on society, and a completely ad-free game is so refreshing. Bought the expansion to support. The game is a fun casual math quiz that lets you practice some mental math exercises while also following proper order of operations (everyone on FB needs to practice). I haven't started the expansion levels yet, but my main feedback for the first 500 levels is that I wanted more challenges that limited operators available to add difficulty.
5 ★ A simple premise with many challenging variations. If you see 2 + 4 x 4 and think 18, you'll love this game. If you think 24, you'll hate it. The game has no in-game purchases and no ads -- even voluntary ones. Gameplay is intuitive with subtle animations. The first time the game interrupted gameplay was after level 50 when it politely asked if I would consider writing a review, which I am happy to do for such a clean, pleasant game. I plan to solve all 500 levels if I can.
5 ★ This game is outstanding. The quality is excellent, the concept is creative, and the experience is fantastic, managing to impeccably straddle the line between too hard and too easy. The result: super fun. Well done. Edit: it should also be mentioned that this game is 100% ad free, which is astonishing. Developer(s), thank you for this absolute gem.
