Roll for 40 Gems.
Switch unlocked classes for free.

Find the booth, roll, and check the result.

1. Walk to the Classes booth near spawn.The report describes a physical stand near the farm’s spawn area. Move your character up to it to interact.
2. Interact to open the Classes menu.Browse the roles and the currently selected preview before spending. If you want to equip a class you already unlocked, select it here for free; you do not need another roll.
3. Press Spin Class at the bottom of the menu.For a random roll, first check that you have at least 40 Gems at the reported price. Forty Gems buys one attempt, not a chosen class.
4. Check both the balance and the class card.According to the report, a registered spin makes your Gem balance fall by 40 and the menu land on a class card.

If the button does not respond and your balance is below 40, you need more Gems first. A non-response with enough Gems does not establish the cause; these balance checks do not diagnose every menu or server fault.

Free Gems: use the right reward entry.

Group reward: FREE REWARD, then CLAIM

The reported reward is 25 Gems once per account. Both a registered like and actual group membership are required.

1. Open FREE REWARD and press LIKE THE GAME.Give the experience a thumbs up on its Roblox page. The report says the panel detects the registered like.
2. Press JOIN THE GROUP and join Garage Games.Join the Garage Games community as an actual member; following or favouriting does not substitute for joining. Both the like and membership must be in place for CLAIM to become active.
3. Return to the game and press CLAIM.The reported success feedback is an immediate 25-Gem increase in your balance. This pays once per account; 25 Gems alone is 15 short of a 40-Gem roll.

If CLAIM does not work, check both the like and completed group membership. If the join prompt says “Unable to join…”, finish joining in your browser or Roblox app, confirm you appear as a Garage Games member, then rejoin the server and press CLAIM again. The guide identifies an unfinished join as the condition to check; rejoining lets the game check membership again. These checks do not guarantee that every claim failure has the same cause.

Daily rewards: open REWARDS

Open the REWARDS menu to access the separate eight-day login track. This is the daily entry; FREE REWARD → CLAIM above is the one-time group reward. The report lists these standard payouts:

Can these rewards buy a roll?

These examples assume a starting balance of zero, an unclaimed group reward, the listed daily rewards collected, no previous spending, no extra Gems or multiplier, and the reported 40 Gems per roll. The arithmetic calculates affordability from the reported values; it does not guarantee a current grant or a particular class.

Day 2 and Day 8 are the largest listed daily payouts: together they provide 620 Gems, compared with 260 from the other six days. You can reach the three-roll example using the stated free rewards without spending Robux.

Reported reward codes provide another separately dated route, with their own validity and reward boundaries. No code grant is counted in these examples.

Optional paid Gems are separate.

The same September 2 report places the Gem shop in the menu system and lists 2x Gems [GP] at 39 Robux. It describes a multiplier on Gems earned afterwards, rather than an immediate bundle. Under that description, a reward earned before purchase would not be doubled retroactively; purchasing before a future eligible payout is the relevant condition.

The report does not itemize every eligible Gem source. These free-reward examples assume no pass; they do not calculate a purchase return or promise doubled amounts for a specific claim.

Source values and instructions: Classes and Gems illustrated report, September 2, 2026; collected September 7. Roll counts and remaining balances are this guide’s arithmetic using those values.

Which classes can you use?

The report lists eight roles. Starter is the starting class; the other seven are the reported random-roll awards.

• Starter
• Pack Mule
• Hay Merchant
• Forkmaster
• Demolitionist
• Prospector
• Drone Specialist
• Ultimate Farmer

Once unlocked, a class stays in your list and can be selected again through the Classes menu without paying again, according to the report.

Choose the action that matches your goal.

Already unlocked the class you want? Select it in the Classes menu for 0 Gems under the reported switching rule. Another random roll is unnecessary for this goal.

Want a chance at a different class? Use Spin Class if you can afford 40 Gems per random attempt at the reported price. It does not buy a named class.

Only have the group reward and Day 1? Keep those 35 Gems and collect more before rolling: you are 5 Gems short. Under the no-spending conditions above, the reported Day 2 reward would bring your total to 155 Gems.

The source gives this roster and unlock process, but no numerical class effects, drop probabilities or measured ranking. For choosing among classes you own, compare their displayed previews and the tool you want to use. That is practical selection advice, not a tested performance order or a “best class” ranking.

The same report says the Farmhouse party menu continues to work whichever class you receive.

Next: decide what to upgrade in your run.

Return to the Farmhouse upgrade decision ↗ for the Hold/Grasp/Speed and tool-cooldown discussion. Relate your next run-cash upgrade to your collection bottleneck; this is separate from spending Gems on classes. The linked guide does not establish a universal best upgrade order or a precise measured Speed effect.
