SPIN THE MARKET WIN THE STOCK
The first slot machine that pays in tokenized stocks. Built on Robinhood Chain, settled by drand.
Every symbol is a canonical Robinhood Stock Token. A winning line pays in the stock on it. The only symbols that are not stocks are the WILD bull and the $SPDX coin.
Deposit USDG
Fund your SPINDEX balance once. Spins settle against it, so no token moves per spin and you never sign twenty transactions to play twenty times.
Spin, drand decides
Each spin is bound to a drand round that doesn't exist yet. The contract verifies the signature on-chain: nobody, not even the house, knows the result early. No network fees: the house covers gas.
Withdraw stock or USDG
Wins land as stock positions, credited at the Chainlink price from the house's stock inventory (restocked in $500 tranches). Withdraw them as tokenized stocks, sell them back to USDG, or cash out. Anytime.
Weekly buyback
Every week, 40% of the house profit buys $SPDX on the market and burns it. Real revenue, no emissions.
Weekly draw in stocks
Staked $SPDX are tickets for a weekly draw paid in tokenized stocks.
Stake to play cheaper
Stake $SPDX to climb from Penny to Mega Cap: USDG rakeback up to 30% of your own losses, up to ×3 airdrop points, the full jackpot.
Points for play
Play and staking both earn season points; your cap rank multiplies them. Season 1 airdrops within two weeks.
| # | Player | Cap rank | Points |
|---|
Lock $SPDX
Stake $SPDX, no lock date. Your loyalty boost grows every day you stay, from ×1 to ×3 in 60 days. Your effective stake (staked × boost) sets your cap rank: USDG rakeback, airdrop points multiplier, Stock Draw tickets. Harvesting or leaving costs something, on purpose.

Season 1 points
Rakeback 0% of the edge you pay
Accrues on every spin as a share of the house edge you pay (3.9% of each bet), in USDG. It keeps accruing if you don't harvest.

Invite friends
Referrals are the biggest lever of Season 1. Every point your friends earn, playing or staking, gives you 25% on top, all season long.

How it pays
- 25%Of every point your friends earn, from play and from staking, for the whole season. Their rank multiplier counts, so a Mega Cap friend is worth three times a Penny one.
- +2.5kPer friend activated: deposited at least $50 and played 100 spins. Activation costs real house edge, so fake accounts don't pay.
- 30→0%Rev-share in USDG on the house edge your friend pays: 30% while they are Penny, then 30% minus their own rakeback as they climb (25%, 20%, 10%), 0% at Mega Cap, where they keep it all.
- +10%For your friend on all their own points, because they came through a link.
| Friend | Joined | Activation | Their points | Your 25% | Your rev-share |
|---|
Referral points count toward the Season 1 airdrop and the leaderboard like any other points.
