Game passes: the 4 anvils
| Game pass | Robux | What it does |
|---|---|---|
| 25x Anvil | 199 | Unlocks the 25x anvil permanently, skipping its Index requirement |
| 50x Anvil | 299 | Unlocks the 50x anvil permanently, skipping its Index requirement |
| 100x Anvil | 399 | Unlocks the 100x anvil permanently, skipping its Index requirement |
| 200x Anvil | 499 | Unlocks the 200x anvil permanently, without the 24 Index entries |
Permanent 2x boosts
The 2x boosts are not game passes: they are one-time Robux purchases made inside the game, and the store marks each one as permanent.
 2x Money (Permanent) | 79 | Double Money from selling rocks |
 2x Machine Speed (Permanent) | 79 | Double the cutting speed of your machines |
 2x AFK Speed (Permanent) | 79 | Double Power from AFK training areas, including anvils and AFK rocks |
 2x Power (Permanent) | 79 | Double mining damage on doors; the Power number on your HUD does not change |
 Ultimate Boost Bundle (Permanent) | 249 | All four 2x boosts, plus one extra Sight level and one extra bag slot |
Is the bundle worth it?
Buying the four boosts separately costs 4 × 79 = 316 Robux. The bundle costs 249 Robux, so it saves 67 Robux (about 21%) and also includes a Sight level and a bag slot that are not sold on their own.
Tick the boosts you want below to compare. If you only care about one boost, a single one at 79 Robux is the cheapest option. Once you would buy four, the bundle is cheaper, and at three it costs 12 Robux more but adds all of the fourth boost plus the Sight level and bag slot.
