Cascade

How to play

Two challenge types alternate inside a round. Higher levels unlock more prompt types.

• Cascade — one chain of arithmetic operations, intermediate values hidden. Enter the final result.
• Dual Track — two chains run in parallel (A and B), and a random final prompt picks which one matters: compare them, state one final value, their sum, or their absolute difference. Do not lock onto one lane — the other is always a possible answer.
