Quick Start

How to Play

It takes 30 seconds to get started. No trading required—just pick your squares and watch the market.

Pick Your Squares

Choose up to 5 squares on the 10×10 grid before 9:25 AM ET. Each square is a unique combination of two stock price digits.

Numbers Are Drawn

At market open, row and column numbers (0-9) are randomly assigned using provably fair cryptography. Now your square has its winning numbers!

Win at Close

At 4 PM, we check the Open, High, Low, and Close prices. The last digit of each price determines the winning square for each prize!
