Cut a Rock Rooms and Floors — Spawn Rates (Roblox)
Cut a Rock on Roblox sends you to deeper floors for rarer rocks. This guide documents the published Room 1 entrance sign and its three printed rates, with a separate status for deeper floors.
The only sign anyone has copied
AllThingsHow reproduces the Room 1 entrance sign as Common 85 percent, Uncommon 15 percent, Nova Prism 0.1 percent. Rocks in that room also show a floating rarity label. The same guide says you reach Room 1 from a teleporter pad in the hub, and that it is the mine a new save uses while saving for the Copper Pickaxe.
A server holds six people. That figure is on the public game record, separate from the sign. AllThingsHow also shows a warning that prevents placing rocks at another player’s plot. The source provides no alternative spawn-rate table for player counts.
| Room | Spawn rates | Rock pool | Status |
|---|---|---|---|
| Room 1 | Common 85% / Uncommon 15% / Nova Prism 0.1% | Common, Uncommon, Nova Prism | 1 source |
| Later floors | — | — | No public source |
What “deeper” means without a map
The game description, newgame, and Bloxodes all say you break through floors and that deeper layers hold rarer rocks, which need a stronger pickaxe and more Power. The cited descriptions do not supply additional named rooms, a floor count, or another spawn table.
If a second public source names the next room, this table grows by a row. Until then, route planning stops at Room 1’s three percentages and the knowledge that a ladder of pickaxes exists to push past it.
Questions
How many rooms are in Cut a Rock?
Not published. The description says multiple floors. Only Room 1 is named with rates.
Do the percentages add to 100?
85 and 15 add to 100. Nova Prism at 0.1 percent is printed beside them. The guide does not say whether 0.1 is inside the 15 or extra. I did not “fix” the arithmetic.
Can six players share one Room 1?
The server size is six. The sign does not say the rates change with a crowd.
