Verified against the spelunky.ai port [v0.1.10](https://github.com/851-labs/spelunky/releases/tag/v0.1.10) on 27 October 2026. *For the box of items, see [Crate](https://spelunky.ai/wiki/crate); for the locked chest, see [Udjat Eye](https://spelunky.ai/wiki/udjat-eye).* The Chest is a carryable item in Spelunky Classic that opens, with up and the attack key, into three or four gems, or one time in twelve a lit bomb. ![A closed wooden treasure chest with a gold lock](https://spelunky.ai/wiki/media/4a03f1981f7c4764/sprites/sChest/frames/0%404x.png) | Chest | | | -------- | ------------------------------------------------------------------------ | | Kind | Carryable | | Effect | Opens into gems, or a lit bomb[^1] | | Object | `oChest` | | Found in | The Mines, The Jungle, The Ice Caves, The Temple, Olmec's Lair, Tutorial | Opened, it spills out a handful of gems, worth from $200 each on the Mines' levels, and sometimes a big one; but now and then it's a trap that throws out a lit [Bomb](https://spelunky.ai/wiki/bomb). It's heavy, like a [Crate](https://spelunky.ai/wiki/crate), and stays where it is, open, once it's been opened. ## Usage **Clip: Chest opened.** The player stands at a chest and presses up and the attack key. The lid opens and four gems spill out, an emerald, a sapphire and two rubies, which he walks over and collects. ([video](https://spelunky.ai/wiki/media/4a03f1981f7c4764/clips/chest/open/clip.mp4)) Pressing up and the attack key while the player stands at a closed Chest opens it: its lid opens, and it stays, open, for good[^2]. What comes out is thrown up at 2 pixels a step and up to 3 to either side[^3]: | Contents | Chance | | | ----------------------------------------------------------------------------------------------------------- | ------------------------------- | ---- | | A lit [Bomb](https://spelunky.ai/wiki/bomb), which explodes 40 steps (1.33 seconds) later, and nothing else | 1 in 12, except on the Tutorial | [^4] | | 3–4 small gems, each an Emerald, a Sapphire or a Ruby, one chance in three | Otherwise | [^5] | | And a big gem: a Big Emerald, a Big Sapphire or a Big Ruby, one chance in three | 1 in 4, with the small gems | [^6] | The bomb's test is that the level number is above 0, and the Tutorial is level 0[^7]. In the clip, a Chest opens into four gems, an emerald, a sapphire and two rubies, which the player walks over and collects[^8]. A Chest is heavy: the player carries it higher than other items, and throws it at 4 pixels a step plus his own speed, rising at 2, or at 4 upward[^9][^10]. Thrown faster than 2 pixels a step, it hurts a monster as any thrown item does[^11]. ## Locations - **Level generation**, in every area: in a nook one block high with a wall beside it, a 1 in 15 chance, once the rolls for a web, the Udjat Eye's locked chest (on the level that has one) and a [Crate](https://spelunky.ai/wiki/crate)'s 1 in 10 fail[^12]. - **The Temple**: some of its rooms have a tile that's a Chest or a Crate, one chance in two each[^13]. - **Olmec's Lair**: a 1 in 15 chance on some of its tiles, the first of their rolls[^14]. - **The Tutorial**, which has one[^15]. - **The level editor**'s `c` tile[^16]. ## Interactions - **[Bombs](https://spelunky.ai/wiki/bomb).** An explosion throws a Chest away from it without breaking or opening it[^17]. - **Shopkeepers.** A trap's lit bomb doesn't anger a Shopkeeper it's near, where one the player lights does: the trap lights it without marking it armed, and only an armed bomb angers him, though one the player is stunned or killed holding is armed as he drops it[^18][^19][^20][^21]. - **Exits.** The player sets down a heavy item, a Chest among them, when he takes an exit, so a Chest can't be carried to the next level[^22]. A trap's lit bomb carried out of the exit, not being armed, goes back into his bombs, where one he lit is left behind[^23][^21][^24]. ## Tips - A Chest that turns out to be a trap gives 40 steps to get clear of its bomb, which is thrown up out of it. - A Chest can be carried before it's opened, so its gems, or its bomb, come out where the player sets it down. ## Trivia - The lifetime count of chests opened goes up on every press of up and the attack key at a Chest, before the code checks that it's closed, so an open Chest counts again each time. It's only written to the game's statistics file: the code that would show it is switched off[^25][^26][^21]. Pressed three times, one Chest counts three[^27]. - A trap Chest plays the sound of a trap rather than the Chest's own[^28]. ## FAQ ### What's in a Chest in Spelunky Classic? 3–4 small gems, each an Emerald, a Sapphire or a Ruby, and a 1 in 4 chance of a big one as well. One Chest in twelve, outside the Tutorial, holds a lit [Bomb](https://spelunky.ai/wiki/bomb) instead. ### Can a Chest explode in Spelunky Classic? Yes. With a 1 in 12 chance, opening one throws out a lit [Bomb](https://spelunky.ai/wiki/bomb) that explodes 40 steps (1.33 seconds) later, and no gems. ### Can you open a Chest twice in Spelunky Classic? No. An open Chest stays where it is, open, and up and the attack key give nothing more from it, though the lifetime count of chests opened goes up on each press. ### What's the difference between a Chest and a Crate in Spelunky Classic? A Chest holds gems, or a trap, and stays once it's open; a [Crate](https://spelunky.ai/wiki/crate) holds one item, such as a Bomb Bag or a Rope Pile, and vanishes when it's opened. ## See also - **Drops:** Emerald, Sapphire, Ruby, Big Emerald, Big Sapphire, Big Ruby, [Bomb](https://spelunky.ai/wiki/bomb) - **Related:** [Crate](https://spelunky.ai/wiki/crate) ## References [^1]: `objects/oPlayer1/step.gml:561-609` [^2]: `objects/oPlayer1/step.gml:561-567` [^3]: `objects/oPlayer1/step.gml:568-605` [^4]: `objects/oPlayer1/step.gml:568-578` [^5]: `objects/oPlayer1/step.gml:580-593` [^6]: `objects/oPlayer1/step.gml:594-605` [^7]: `objects/oPlayer1/other_animation_end.gml:87-94` [^8]: Clip chest/open [^9]: `objects/oItem/step.gml:44-56` [^10]: `scripts/scrUseItem.gml:609-635` [^11]: `objects/oItem/step.gml:256-350` [^12]: `scripts/scrTreasureGen.gml:47-72` [^13]: `scripts/scrRoomGen4.gml:359-363` [^14]: `scripts/scrRoomGen5.gml:177-179` [^15]: `rTutorial`, as the room editor placed it [^16]: `scripts/scrCreateTileObj.gml:285-288` [^17]: `objects/oExplosion/collision_oItem.gml:30-36` [^18]: `objects/oPlayer1/step.gml:570-577` [^19]: `objects/oBomb/step.gml:6-17` [^20]: `objects/oPlayer1/step.gml:1714-1720` [^21]: Quirk 1 (docs/quirks.md) [^22]: `objects/oPlayer1/step.gml:815-820` [^23]: `objects/oPlayer1/step.gml:821-831` [^24]: Replay `fidelity/replays/item-chest-trap-bomb-unarmed.txt` [^25]: `objects/oPlayer1/step.gml:561-565` [^26]: `objects/oGame/draw.gml:137-155` [^27]: Replay `fidelity/replays/item-seed-13-chest-tally.txt` [^28]: `objects/oPlayer1/step.gml:578-581` ### Source code - `objects/oChest/create.gml` - `objects/oPlayer1/step.gml` - `objects/oItem/step.gml` - `scripts/scrUseItem.gml` - `scripts/scrTreasureGen.gml`
