No revenue estimate for APPLE — its rating/review counts don't calibrate to sales the way Steam's do. The Steam version is estimated at $7.7M — a different platform, not this one.
[We recommend a total device RAM of 4GB or higher; otherwise, the app may crash due to insufficient memory.] In Backpack Battles, you fight with your backpack full of items! It matters what you buy, and especially how you place them. The smarter you place your items, the stronger you'll be! Items come in different shapes, sizes, prices, and rarities. Combine them into even stronger equipment: brew powerful potions, craft legendary weapons, or even hatch a dragon friend! Face the backpack builds of other real players. See what they came up with, and counter them to win. Test your limits in Ranked Mode and climb the leaderboard! Or relax in Unranked Mode with low pressure. Both modes have no time limits, so take your time to organize your backpack! Join our community for discussion and support!

Prices
Each in the currency that store quoted — not converted: the gap between two rows is the publisher's pricing, not an exchange rate.
14 of 15 markets; the rest we haven't asked for this title, not markets where it is unavailable.
Availability
We put this game to every storefront we collect. A market that answered not sold has told us something about the game; a market we never asked has not, and the two are never drawn the same.
Charts
Each storefront's own chart, in its own country — the closest public signal to sales where none is published. A country missing from a list is one we don't collect there, not one where the game doesn't chart.
No United States chart position — it charts only in the markets below.
Ratings
Each storefront's own ratings counter and average — separate, overlapping audiences, never added together.
Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
Reviews, worldwide (the counter carries no country): 0.43/day in the week to Aug 6 → 1/day in the week after.
Too few observations to say whether a discount moves this store's chart at all: across the last 30 days App Store · Top Paid · Japan has just 11 day-to-day chart moves that followed a price cut, against 2,669 that did not. We are publishing the count instead of a direction — 20 is the fewest we will draw a conclusion from, and price collection outside the United States began on 6 August 2026.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.

Stats
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.

14 on sale1 answered “not sold”0 we did not ask
The 1 “not sold” market is read from the App Store price pass of Sep 13: that day the store answered for this game elsewhere and gave no price there. The 14 priced markets are the same rows as the table above — each the latest price we hold, dated here when it is older than that pass. The 0 marked “not asked” were not put to this store at all — either it has no storefront there or we do not collect it yet, and neither is a statement about the game. A refusal is a refusal on one day; a store can list a title again tomorrow.
Latest in each market: best JP #48, worst AU #94 · 9 markets collected
14 of 15 markets; the rest gave no counter or aren't reached yet, not markets where nobody rated it.
