### 1/5 — Don’t get

*2026-07-28, version 1.5.4*

There’s an add every 5 seconds, you can’t even get through one level without 3 different ads

### 1/5 — Advert heavy

*2026-07-11, version 1.5.4*

Cannot progress past lv10 unless you buy ad free version, as the same stupid ad with no exit button pops up - waste of time unless you pay to pay

### 1/5 — More ad then game

*2026-06-28, version 1.5.4*

The free version is unplayable with how many ads there are.

### 1/5 — I counted 13 adds while playing 1 single level

*2026-06-11, version 1.5.4*

I get the point of having adds however bombarding it with adds while you are playing and 13 of them.. just horrible

### 2/5 — Ads!!

*2026-06-08, version 1.5.4*

Ads galore. Every! 30!Seconds! I get it. But makes the game extremely not fun!

### 1/5 — Ads

*2026-06-06, version 1.5.4*

Paid for no ads and still getting them. Want a refund.

### 2/5 — Far too basic

*2026-06-03, version 1.5.4*

This gets boring really quickly. The high number of reviews is because it prompts you for one very quickly. If you aren’t already familiar with Shikoku you might be impressed by then.

### 5/5 — Pattern Fiend

*2026-05-29, version 1.5.4*

This game will cause you to think differently about Tetris! It’s so easy to figure out but requires mental fluidity.

### 1/5 — Ads actually make it unplayable

*2026-05-22, version 1.5.4*

I don’t mind ads on a free game but ads that happen in the middle of a game ever few strokes? Not only are you advertising other games that aren’t yours but you make your own game unplayable. Didn’t even keep it installed long enough to let it grow on me to contemplate buying it. You need to make ads annoying enough that I may pay to have them  gone, not so annoying I’ll delete your app in literally 5 minutes after trying it.

### 1/5 — Too many ads

*2026-05-13, version 1.5.4*

Literally horrible with how many ads it makes it unplayable
