### 5/5 — シュルテテーブル

*2026-01-17*

PCでは見つからなくなったアプリがスマフォに着ているのを見ると感慨深いです
人間の瞬きは3秒に1回が平均と考えると3x3で3秒以下を目指すのが負荷が少ないかなと
そこから9マス増えるごとに3秒掛ければ大体の目標が見えてくる気がします
画面が小さいのであまり根を詰めない方が良いです

### 1/5 — Horrible Ratings Trick

*2023-04-03, version 1.0.7*

The game seems fine, EXCEPT, after a few turns, one MUST rate it….and it states that a 5-star rating will reduce ads. But the game will not progress unless you give it a rating.  Deleting immediately.
