### 2/5 — UPDATE 2017 plz| update 2025 plz

*2025-06-14*

I LOVE this game! But theres some glitch where once I die, an ad jumps up, then I am booted out of the app. When I reopen, it's like its opening for the first time. If you guys could take another look at this one, I'd really appreciate it. It probably just needs to be updated to fit this iOS, or for the newer phones or something. Thx for making a really fun game!

### 5/5 — unavailable

### 5/5 — Please update your game

### 5/5 — Please update this I need it back in my life

*2021-05-30*

Pls

### 3/5 — Awesome & terrible

*2020-02-15, version 1.8*

This is a great game, one of 5 of its type (split screen simultaneous mini games) I've downloaded and BY FAR the best; it's a wonderful brain workout that I use to help sharpen my focus, attention, and observational skills. There's a nice variety of games at the perfect difficulty level, and the game/graphics work well on my old iPad mini (1) with iOS 9.3. 
   I would definitely award it 5 stars except for, as everyone else says, THE FRICKIN' POP UP AD THAT INTERRUPTS GAME PLAY. I've never seen such an intrusive ad in any app, ever; it pops up every COUPLE MINUTES, often in the middle of game play and closing it frequently causes me to lose one or both mini challenges. This is TERRIBLE and at this point I'm unsure if I'll continue to play this game or not.  
   If the problem is fixed I will change my rating to 5 stars and download anything else offered by this developer. I have little hope though since it's already been years.

**NOTE: one reviewer suggested playing in airplane mode; this does NOT work to avoid the pop-up.  :(

### 3/5 — Pls update

*2019-01-26*

### 1/5 — Needs update to work with iOS 11

*2017-10-11*

This game is awesome and I really enjoy it, but it doesn't work with iOS 11.  Can you please update it so I can keep playing?  Thanks!
