### 5/5 — Klinkie approves

*2016-02-10*

this game is a game Klinkie123 approves of

### 5/5 — Eels

*2015-08-26*

Eels are cool make more challenging

### 2/5 — eels

*2015-03-06*

I don't think that you needed the eels at all. They get really annoying

### 5/5 — Best game ever.

*2012-08-29*

I love this game. I love lobsters. So.much.fun. You don't know how much time I waste playing this game but at least I'm doing a little bit of math! It's better than temple run you learn squat from temple run.

### 2/5 — Great game, needs work for classroom use

*2012-02-14*

Great game! However, the fact that my students are unable to save their progress or start in different parts of the game, makes the app frustrating and not useful. If there was a way to jump between levels and save progress, this app would receive a 5 star rating!

### 2/5 — Crashed

*2012-01-22*

It crashed during my highest score and now I deleted it.

### 5/5 — Super

*2011-12-21*

I love this app! My students love using this to freshen up their number line skills and fractions...I love the eel cutting because it changes the mind up and than back to diving.

### 4/5 — A good little game

*2011-05-30*

I work in education and the kids I work with one on one really enjoy this game.  It is a great way of reinforcing number sense.
The only thing I would change would be to be able to change the timer, make it longer for kids who find it more challenging.

### 4/5 — Bugs fixed great game

*2011-05-25*

Played the game on an ipad2 and it works great.  It didn't lock up at all.  Loved the graphics.

### 1/5 — Doesn't work

*2011-02-11*

Locks up and shuts down as soon as you tap play game. Too bad, looks really cool otherwise.
