Each daily grid is 4×4. You start top-left, finish bottom-right and can only move right or down, which gives exactly 20 possible routes. A solver checked that exactly one of them hits the target, so there's no arguing over the answer.
The answer is shown as arrows (→ ↓) below a gap. It's good practice for quick mental addition and planning ahead.
