クイズサバイバル　-暇つぶし脳トレ言葉ゲーム-

How fast this game is gaining ratings — the activity signal available where a store publishes no sales or install numbers.

Measured from our own daily snapshots, not reported by the store. Deliberately not converted into sales: a one-tap rating's ratio to copies sold is unknown on this platform, and guessing it would be worse than leaving it out.
