### 2/5 — Game is horrible

*2016-06-17, version 2.4.3*

The concept of this game is based on luck, meaning it is NOT a puzzle. Also, how the numbers appear is not random, they appear, every single time, without fail, exactly where you need them NOT to go. It is a very fun concept, though, and with a few updates, I may download it again.

### 5/5 — Very clever little game

*2016-04-06*

I think this is such a cute game. The other reviewer got stuck, as his first game had no match. If that happens, just move a block, and other numbers will appear. I find it challenging as the board fills v quickly, but by arranging tiles so consecutive numbers are next to one another, it is possible to get close to 12. My best so far is 9. I own all 4 gamebra.in puzzles, they are all wonderful ( hocus, rop, joinz, and twelve ). Please persevere with twelve, it is infuriating but fun. I'd give 6 stars for ingenuity here. I think it similar to merge in strategy, but this was released 3 years earlier . Disgusting how people steal others ideas.

### 2/5 — Not the hardest puzzle

*2016-03-16*

If you've beaten 2048 you can beat this. Pretty, but not overly challenging.

### 2/5 — Fun game! But...BUGGY.

*2016-01-16, version 2.4.3*

Was really enjoying this game...until it started behaving erratically. Visiting the reviews here, it seems this is a common experience. Sad. Not sure I'll keep the game if it's so unreliable.

### 1/5 — Didn't last 30 seconds...

*2016-01-10, version 2.4.3*

I was less than a minute in when this app became completely unresponsive. I couldn't move the numbers, push the pause button, nada. I tried everything I could think of to fix it, but to no avail.

Could have been a fun game, I'll never know...

### 2/5 — So. Many. Bugs.

*2016-01-09, version 2.4.3*

Too many bugs. The numbers just disappear even if I restart the app. The numbers won't always move. After I deleted and reinstalled it worked like it should for about 5 games or so, then it started to bug out again. Sorry but it's unplayable for me.

### 4/5 — Am I missing something?

*2015-11-02*

Ok, so I persevered, and it turns out of you have no matching numbers you have to arbitrarily move a number to a different square and it gives you more numbers. This wasn't in the tutorial and should be clearer, hence only 4*

HOWEVER... This game is actually highly addictive and a great concept. You should definitely update your tutorial though!

Old review: It seems to me that this game is fundamentally impossible... The instructions are minimal but from what I can glean, I'm supposed to match the same numbers to add one to them and get a new piece. This would be fine, but due to the random nature of the game I end up refreshing the level 10 times every time I start because inevitably there are no matching numbers at all on the first deal.

Either this is a major flaw in the game, or the guys need to make some much clearer instructions...

Good luck to anyone else.

### 5/5 — Good

*2015-02-26*

Good game!

### 4/5 — 👏

*2015-02-15, version 2.3.5*
