How this model works

Normal dice are uniform from 1–6 on a 26-tile board. Tile leveling, start-tile item rewards, Twin Star limited missions, and rolls spread over all seven days are included.

Expected values are averages, not guarantees. Teammate rewards, bombs, gifts, and team-dependent effects are excluded. Random Gem payouts from Lucky Pouches are excluded from expected value; Lucky Pouch quantities are shown separately.

Your site State Phase selects the matching Twin Stars reward bracket and complete Polar Shop inventory. Rolls, costs, pack paths, and Adventure Coin EV do not change by phase.
