Very annoying and prevents me from playing regularly, but other than that the game itself is great and very addicting ### 4/5 — 100‎%‎‎%‎‎%‎ niiice *2017-12-13, version 1.2.4* ✌🏽 ### 5/5 — Great game *2017-07-31, version 1.2.3* Kills time... Addicting at first. The "Restart" button could use a "ARE YOU SURE?" pop-up BEFORE IT RESETS YOUR ENTIRE GAME. I'm up to 310,00 points and should be higher but my wife accidentally hit thay button and it wiped the entire game. I don't know if this has been incorporated yet, because i haven't messed with it since. Otherwise a fun game. ### 5/5 — New 2 game *2017-07-22, version 1.2.3* Kinda fun!!!!!! ### 5/5 — Math Skills *2016-08-03, version 1.0.2* So far I like this better that 2048. ### 5/5 — Great game !!! *2016-06-26, version 1.0.2* This is a fantastic game !!!
