Crystal Cave

It is a free Roblox simulation tycoon by Curseddd Games. Anime characters break rocks for ores, you sell those ores for cash, and cash buys levels, pickaxes, mutations, and the research that opens the next mine. Servers hold 12 players.

No. Pickaxes are gear for the anime miners on your plot. You click early rocks yourself, then deployed characters mine and a higher pickaxe multiplies the miner who holds it. Use Equip Best after you buy a new batch.

Finish the current zone research board to 100 percent, then pay the cash fee on the mine gate. Finding every index entry is not the requirement. If the gate stays shut, the board is incomplete or the fee is still unpaid.

Yes. Characters stored in the chest or inventory can show up in the shop sell list. Sell ores on purpose and leave miners out of that selection. Auto Sell also needs a per-item toggle so a new character is not converted by accident.

The experience is free on Roblox. Optional passes speed up mutation rolls, drop luck, walk speed, or selling. They do not skip the rule that each zone research tree must reach 100 percent before the next gate can be bought.
