Dual Decode

A minimalist dual-code puzzle. Solve two boards at the same time.

Each board hides a 4-digit code with no repeated digits.

• Green = correct position
• Yellow = wrong position
• Dark Grey = not present

Use Split to send different digits to each board.
You only have 2 Splits per game — correct guesses (Green) give you free extra Splits.
