Dota 2 treasure opening simulator

356 treasures with their regular and rare tiers and live item prices. Open any of them for free and see how much of every 100 you spend comes back.

Every opening gives one regular item, and Rare, Very rare, Ultra rare and Cosmically rare items are extra rolls on top. Since October 2018 the treasure preview shows each escalating item’s odds by opening: a Rare item starts at 1 in 2,000 and is certain by the 40th opening, an Ultra rare starts at 1 in 100,000, and each item’s counter resets when it drops. The simulator can’t see your counters, so it uses the long-run averages of those tables — 7.74% per Rare, 4.51% per Very rare and 2.26% per Ultra rare item — and the fixed 0.0004% for Cosmically rare items, with one item per opening.
