According to this app it has not been update in 4 years. ### 2/5 — Frustrating *2014-08-22* And not frustrating because it's hard, frustrating because every time I get to about 23-24, it stops and says "game over" even with plenty of time left on the clock. ### 1/5 — Update brings Ads *2014-08-17* It's a new layout if you consider the addition of an ad banner to the footer a new layout. I'll likely delete this app even though I find the game itself enjoyable. The developer needs to know their description of the update is the reason I am deleting it. ### 4/5 — Layout fixed bull...ads added! *2014-08-16* Excellent game! Great little tag for the update. Layout fix...aka ADS ADDED! Definitely know I suffer from dyslexia now. This would be nice to have different levels or times to try and beat the game under. I've played over 200 games with a max of 58 so far. Can't put this game down once I start. ### 5/5 — SO addictive! *2014-08-16* My mathematical brain has fallen in love with this. It is simple, yet engaging. Only request would be the ability to switch color schemes. ### 1/5 — Like it, but *2014-08-12* I really like the game, but I'd like to suggest a game play fix. If you click on a number just as the board gets scrambled, it ends the game because you actually clicked on the wrong number. Please do something like adding a cell delay on the next number so it won't register a tap just as the board scrambles. I'll change my review rating to 4 or 5 stars when you acknowledge my comment/suggestion. Thanks. ### 3/5 — Entertaining for sure *2014-08-11* I'm not sure if mine has a bug but why will the clock run out of time at random times? Half the time I don't even get 60 seconds and sometimes I tap a number and it automatically ends my game. Is there something I'm missing? ### 4/5 — 81 numbers *2014-08-10* Really like the game, the timer is very distracting. Wish I could hide it, as it is I cover it up. ### 2/5 — Ehh *2014-08-09* I got this game on app gratis today. I hope this doesn't usually cost ¢99. I simply cannot handle it. If you like boring, addicting, time-killers; this is for you. I played like 20 games then deleted the app. ## Frequently asked questions about 81 Rush ### What is 81 Numbers? 81 Numbers is a free board puzzle game played on a 9x9 grid.
