The problem
Burying drop probabilities behind hidden buttons hurts player trust and friction.

Tiered pull increments
1x for early gameplay, 3x for mid-tier players, and 10x for bulk late-game rolls.
- 03
Separated currency rows
Standard rolls and premium rolls isolated into dedicated visual rows to avoid accidental currency spend.
