SPINDEXRobinhood Chain

SPIN THE MARKET WIN THE STOCK

The first slot machine that pays in tokenized stocks. Built on Robinhood Chain, settled by drand.

96.1%RTP over 40M simulated spins
9Robinhood Stock Tokens in every spin
$0network fees: the house pays the gas
1,000×max win on a single spin
Real stocks on every spin

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.

How it works
1

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.

2

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.

3

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.

What $SPDX does for you
BURN

Weekly buyback

Every week, 40% of the house profit buys $SPDX on the market and burns it. Real revenue, no emissions.

STOCK DRAW

Weekly draw in stocks

Staked $SPDX are tickets for a weekly draw paid in tokenized stocks.

CAP TIERS

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.

SEASONS

Points for play

Play and staking both earn season points; your cap rank multiplies them. Season 1 airdrops within two weeks.

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.

    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.
