Assumptions (click to expand)
26-tile board, ~70 coins/roll (calibrated on 3 samples: 65 at 127 rolls, 71 at 159).
Pip value and tile targeting don't change coin income, so coins are treated as a function of rolls (normal dice can't pick pips).
Progress rewards (100 pips→500 / 350→2,000 coins) and shark rewards are added as a step function; both require rolling.
The 1,600-pip=10,000-coin rung (~457 rolls) and 3,500-pip (~1,000 rolls) are out of normal reach and excluded.
Each crystal die draws the high-treasure distribution (avg 500, not a guaranteed 2,000); on laps it buys only ~0.23 laps each.
The 700-pip badge is excluded (coin value unconfirmed).
Free dice: 16/day (daily 1 + missions 12 + ranking 3) + 20 one-shot (route 4 + panel 16) = 132 over 7 days.
