Mystery Boxes: free, with the odds on screen
Mystery Boxes in RunBattle sit on the city map, and closing a loop around one makes it yours. Each box has a rarity: common 70%, rare 22%, epic 7%, legendary 1%. Every box holds coins or an item, none are empty, nobody can buy one, and the app shows the odds before you open it.

How do you get a box?
Find a box on free ground and run a loop that closes around it. The box goes to whoever closes that loop, the same way the ground inside becomes a zone.
A free box doesn’t wait long. If nobody claims it, it disappears after 48 hours.

What happens to a box inside someone’s zone?
It goes to the zone’s owner after 24 hours. Take the zone before then and the box comes with it.
The map feed flags a box that is about to go to its owner 3 hours before it does, so you can see which take-overs have a box riding on them.

How do the odds work?
Two rolls decide what you get. The first happens when a box appears on the map and sets its rarity: common 70%, rare 22%, epic 7%, legendary 1%.
The second happens when you open the box and picks what is inside. These are the shares the app shows on its odds screen:
- Common: 15 to 40 coins (85%) or a common item.
- Rare: 50 to 120 coins (75%) or a rare item.
- Epic: 150 to 300 coins (60%) or a zone style (40%).
- Legendary: 400 to 800 coins (50%) or a legendary item (50%).
- An item you already own turns into coins at its shop price.
What does a 1% legendary chance mean in practice?
On average, one box in 100 is legendary. Each box is rolled on its own, so you can get two in a row, and you can also go a long stretch without one.
Why we show the odds
Apple’s App Store rules require apps to disclose the odds for loot boxes sold for money. Ours cost nothing, and we show the odds anyway, because you should know what a box can hold before you open it.
The odds screen is in the app before you open anything, and the odds are the same for every player.
What boxes don’t contain
There is no money in a box and nothing with cash value. You get coins or an item for how your map and runner look, and both stay inside the app. You can’t withdraw them or sell them.
Where and how often do boxes appear?
Boxes appear in any city. The map is split into cells of about 2 km. A cell that someone ran through or looked at on the map in the last 72 hours gets up to 4 boxes a day and holds at most 3 at once.
A box lands on a RunPoint or on ground someone has already run, no sooner than 2 hours after that run. A cell with neither gets no boxes.
Missions pay boxes too: weekly and streak missions can give one, and where an area has RunPoints, the first one you pass each day gives a common box.
Opening one
Your boxes wait in a list in the app until you open them. Press and hold, the box cracks open, the reward shows up and the coins fly into your wallet. Coins from boxes sit outside the daily cap on run coins.
Are boxes fine for teenagers?
There is nothing to pay for. Boxes are free, they can’t be bought, and what drops has no cash value, so there is no spending to watch over.
