The four rigs side by side
| Rig (Robux) | Label and cost per point of multiplier |
|---|---|
| Inferno Rig (59) | x10 training rig. 5.9 Robux per x. |
| Galaxy Rig (249) | x25 training rig. 10.0 Robux per x. |
| Rainbow Rig (499) | x50 training rig. 10.0 Robux per x. |
| Hacker Rig (1,199) | x100 training rig. 12.0 Robux per x. |
Which rig is the best value
Going by the labels alone, the cheapest rig is also the best value for each point of multiplier: Inferno costs 5.9 Robux per x and every bigger rig costs more per x (Galaxy 10.0, Rainbow 10.0, Hacker 12.0). Galaxy and Rainbow cost almost the same per x, so the choice there is how big a multiplier you want, not how much you save.
That is arithmetic on the store prices, not a test. We haven't measured how fast any rig trains, and we don't know if a bigger rig replaces a smaller one or adds to it, so we don't claim Hacker is 10 times better than Inferno in play.
Passes that are not rigs
DREADNOUGHT (999 Robux), PHANTOM (2,299) and ORBWEAVER (399) have no description on the Roblox page, so we don't call them rigs. The game description says there are 12 armatures up to GENESIS. In the RoBros footage the shop panel shows armature packs: Dreadnought adds 6 arms with grip and speed (800 Robux on that panel) and Orbweaver adds 4 arms (320 Robux). Those prices differ from the store pass list, so check the price in the game before you buy.
For how training, arms and grip fit together, see the Grip and Arms page. For every pass and price, see Game Passes.

- The pass page, not this page, is the source for what a rig does. If it changes, trust the store.
