Odds
Artifact draws are the only thing in Crushteroid you can pay for whose result is random. This page gives their exact rules. The game shows the live odds for your own pool before every draw and on the Artifact Supply offer.
Game content version p3.0-c1. The rules below come from the game server's content and code; the server decides every draw. This page is updated whenever a content release changes them.
Artifact draws
- You choose a pool of exactly 3 artifacts you have discovered. Your first pool is Sun Shard, Echo Lens and Iron Heart. The same pool and odds apply to every key, earned or bought.
- One artifact key opens one draw. A draw gives one copy of one eligible artifact from your pool, plus 5 artifact dust.
- An artifact is eligible while its rank plus its banked copies cannot yet reach your current rank cap. Once an artifact can be funded to the cap, it leaves the pool's odds.
- Every eligible artifact is equally likely. There are no rarity tiers, no hidden pity counter and no guaranteed result, and the odds never depend on what you have spent.
| Eligible artifacts in your pool | Chance for each |
|---|---|
| 3 | 1 in 3 (33.33%) |
| 2 | 1 in 2 (50%) |
| 1 | 1 in 1 (100%) |
| 0 (all three can reach the cap) | No draw: the key is kept. Choose another pool of discovered artifacts. |
- Opening 10 or 100. The server makes that many single draws one after another, each with the odds at that moment, and charges only the keys actually used. If every artifact in the pool can reach the cap part-way through, it stops and keeps the rest of your keys.
- Odds are fixed before you spend. The game shows the odds and asks the server to pin them. If they changed in the meantime, nothing is spent and you are shown the new odds first.
- No rerolls. The server records each result before the game shows it. Reconnecting shows the same result.
- Copies. Your first copy of an artifact unlocks rank 1. Later copies are banked for rank-ups or can be dismantled: 1 banked copy gives 2 dust. Ranks you own are never dismantled.

Copies and dust per rank
Reaching a rank uses banked copies and artifact dust. Rank 1 comes free with the first copy.
| Rank | Copies used | Dust used |
|---|---|---|
| 1 | 1 (first copy) | 0 |
| 2 | 2 | 4 |
| 3 | 3 | 6 |
| 4 | 3 | 6 |
| 5 | 3 | 6 |
| 6 | 4 | 8 |
| 7 | 4 | 8 |
| 8 | 5 | 10 |
| 9 | 6 | 12 |
| 10 | 6 | 12 |
| Rank | Copies used | Dust used |
|---|---|---|
| 11 | 7 | 14 |
| 12 | 8 | 16 |
| 13 | 9 | 18 |
| 14 | 10 | 20 |
| 15 | 11 | 22 |
| 16 | 13 | 26 |
| 17 | 15 | 30 |
| 18 | 17 | 34 |
| 19 | 19 | 38 |
| 20 | 22 | 44 |
Refinery board (not sold)
The refinery is not a purchase: it processes the ore you collected. Each piece takes a path the server fixes when the flight closes, makes 8 left-or-right steps and lands in one of 9 bins. The number of right steps decides the bin, so the odds for every piece are:
| Bin | Multiplier | Chance |
|---|---|---|
| 1 | ×8 | 1 in 256 (0.39%) |
| 2 | ×4 | 8 in 256 (3.13%) |
| 3 | ×2 | 28 in 256 (10.94%) |
| 4 | ×1.5 | 56 in 256 (21.88%) |
| 5 | ×1.25 | 70 in 256 (27.34%) |
| 6 | ×1.5 | 56 in 256 (21.88%) |
| 7 | ×2 | 28 in 256 (10.94%) |
| 8 | ×4 | 8 in 256 (3.13%) |
| 9 | ×8 | 1 in 256 (0.39%) |
Bins are numbered from left to right: 1 and 9 are the outer edges, 5 is the centre.
Average multiplier of the base board: 895/512, about ×1.75. Upgrades and artifacts change values, not these odds. A Catalyst booster (sold in bundles or for gems) multiplies one haul's refinery value by 1.5; doubling a haul adds pieces. Neither changes the bin odds.
Purchases with fixed contents
Everything else you can buy always gives exactly what its offer shows:
- Twin Ignition starter: the next Twin Ignition rank and 300 gems, once per account.
- Yield Reactor: permanent ore ×2, once per account.
- Fleet Amplifier: permanent main damage ×2.5 and 1,200 gems, once per account.
- Sector Fund: the milestone rewards of the current three-region chapter, once per chapter.
- Power Card: 30 days, 300 gems at once and 60 gems a day, ore ×1.25 and no ad needed to double a haul or continue a flight. It does not renew automatically.
- Power Pass: the premium lane of the current 28-day pass (its keys are listed above).
- Daily Supply: 1 Overclock, 1 Catalyst and 150 gems, once per UTC day.
