Fair monetization without paywalls - haven’t dropped a dime after months of playing but may well do to support the dev. ### 5/5 — Whiz *2018-07-14, version 1.1.4* Yes I agree with Miss Cathexis! ### 5/5 — Axon *2018-06-13, version 1.1.4* I have just download this game and find it very addictive in fact, I have surprised myself at the amount of puzzles I have succeeded at. Brilliant.🐶👏👏👏👏💜💜 ### 3/5 — Mystery Grid Gone *2018-02-21, version 1.1.4* While I absolute love these type of games and enjoy playing through this app, my access to the mystery grid has been unavailable for months now. When I downloaded the app initially I worked my way up and was able to participate in the grid, but after being reset through one if the updates despite being at the highest level, I still can’t access the mystery grid. At I the only one? ### 5/5 — For students. *2018-02-03, version 1.1.4* I like this game. My students and I play together. ### 4/5 — Favorite Game So Far *2018-01-17, version 1.1.4* This is the only game I’ve downloaded and kept on my phone for more than a few months. Even though the game boards repeat there are so many that you don’t remember them and the Explorer board keeps it fun because it’s basically looking for the prize in the cereal box 😋 Only gave it four stars because there are some glitchy boxes on certain game boards that they still have not fixed. ### 5/5 — Sneakily Addicting *2017-11-21, version 1.1.4* I love this game. The graphics are great, colors vibrant, sound effects very satisfying. I love the puzzles and feel like their difficulty is just right. There are a few really hard ones, but you’re never stuck without the ability to skip them if you’re patient. If you’re not, you can purchase gems, if you can’t, just wait a bit. I have bought gems to support the developers. I think that other than a few glitches (and, please, please....an ability to skip the tutorial) it’s very well executed. Other than tickets for multiplayer, there are no annoying “lives” that you have to wait for. I could play for hours as the puzzles are always different. So far no “unsolvable” puzzles. Love the ratings, love the stats, love multiplayer, love, love, love....Great job!! ### 5/5 — Excellent *2017-11-16, version 1.1.4* Le jeu que je cherchais depuis longtemps.merci Bigpoint. ### 2/5 — Good fun but updates are annoying *2017-10-28, version 1.1.4* I really enjoy playing and the puzzles are increasingly challenging. But nearly every time the app updates, all my progress is erased. Additionally, there’s never an option to skip the tutorial. So in two months, I’ve had to start over 3 times and have suffered through the opening tutorial about 8 times. If it erases my data again, I’m deleting the app. ### 1/5 — Waiting for server response ................. *2017-10-11, version 1.1.4* Good game but you won't get your free stuff or reduce time on opening card packs because you are constantly waiting for server response and it rarely connects. And yes I have great wifi so it's not my connection. ## Frequently asked questions about Axon ### What is Axon?
