Place a number from 1 to 10 in the red circle and each yellow circle. Start at the red value, then follow each branch’s operation using the current result and the next yellow-circle number. Branches marked with = must match the fixed number in the green circle.
Red start — fill this in

Use each number card from 1 to 10 once: one card for the red circle and nine for the yellow circles. Drag each card onto a circle, or select a card and then a circle.
Use the numbers 1 to 10 without repeating any. Start at the red circle, then follow the branches from the center: left to the two left-side results, down to the bottom result, and right to the three results on the right.
