Nummit #189 — target 643 (Hard)

This was the daily Nummit puzzle for September 6, 2026. The six numbers were 50, 25, 4, 8, 2, 6 and the target was 643. It is rated Hard, and the shortest solution takes 5 steps. Playing it here is practice mode, so it won't change your daily streak.

About this puzzle

  • The numbers: 2 large (50, 25) and 4 small (8, 6, 4, 2).
  • The target: 643 is a prime number, so it can't be reached by multiplying two smaller whole numbers. The nearest starting number is 50, 593 away, so you have to build the target rather than start next to it.
  • Difficulty: It is rated Hard because the shortest route needs 5 operations and the target sits far from every starting number, so there is no quick shortcut.
  • Tip: With 50 and 25 on the board, try combining the large numbers first and fine-tune with the small ones.
