### 3/5 — Great App but…

*2026-03-27*

*2026-03-14*

This actually a great game and I will revise my rating if the ad for 3d wool escape is no longer shown. It’s utterly disgusting.

### 2/5 — The ads kill this game!

*2025-12-31*

Used to love this. The game itself is great BUT  ads before after and during the game, some are a full 2 minutes and more. I’m done.

### 1/5 — third time this week where ad is just blank black page

*2025-11-27*

And then can’t get back to game… so have to delete app and reload. Very annoying

### 4/5 — Color

*2025-07-20, version 3.1*

Love. Color coded

### 1/5 — 是有毒嗎

*2025-05-07, version 2.9*

沒廣告卻爆炸Lag，真厲害

### 5/5 — Little Ranger

*2025-05-05*

Love it! Challenging! Enjoying the puzzle!

### 1/5 — Delays filling box with number

*2025-03-07*

I love this game, but it frustrates me when I often have to keep tapping a box and the number doesn’t enter. It also lags when switching from On to Off with guesses, causing needless entry errors. 
I tried clicking on app support, but it is in Asian characters, as are many of the ads. Sorry. To annoying. Deleted.
