Pot of Gold: free idle builder game for XP

Press Spin to turn the reels by hand and earn coins. Coins live inside this game only — they carry no cash value and cannot be withdrawn or exchanged.

Spend coins on three upgrades: a bigger multiplier, faster reels, and a collector who keeps the reels turning without you, even while the tab is closed.

Coming back after time away pays out the coins your collectors earned while you were gone, capped at eight hours so a long absence cannot outrun the game.

XP is only awarded when your total coin production crosses a 500-coin milestone — never for spinning itself, and never tied to any real-money outcome.

There is no purchase, no deposit and no prize beyond XP on the site leaderboard.

XP is the score kept on this site. It has no cash value, cannot be bought, cannot be exchanged for anything at any casino, and exists so that the daily, weekly and all-time tables on the leaderboard have something to rank. Every game on the free games shelf pays into the same balance, as do the trainers in the academy, the daily search bonus and the hidden hat.

Pot of Gold pays XP for the events listed in the rules above and for nothing else. There is no return-to-player figure because there is no player money: the reels are tuned to be readable and fun, not to model any real slot, and nothing that happens here is a promise about how a real game behaves. The house edge calculator is where the real numbers live.

Progress is saved in this browser under a ticket you name the first time XP is earned. Clear the browser and the ticket is gone, so keep the nickname somewhere. Balances sync to the table every few seconds while the tab is open, and a stake lost in the vault comes off the table like any other loss.
