*2026-06-26, version 1.1.5*

Never Give Up!!

### 2/5 — Obnoxious ads, frequently crashes

*2026-05-23, version 1.1.5*

These are the most obnoxious ads I’ve seen in a game.  They REQUIRE interaction and are 60 seconds long.  Frequently the game crashes and the rewards aren’t even issued.  Additionally, the ga,e crashes to the home screen frequently.  There are better options.

### 1/5 — became religious

*2026-05-17, version 1.1.5*

So this will sound silly, I know, but this app was good in the beginning and then I began to see more and more religious ads. I want to play a game, not have religious agenda or games for that matter thrown in my face every time I want to play soduko. I deleted the app and found a different puzzle app.
