DAY 366

Today’s Challenge

You are playing Roll3Dice and have rolled the numbers 2, 5 and 6 with your three dice.

Using 2, 5 and 6 once each, with + – × ÷ available, it is possible to make seven target numbers from 1-10, as shown below.  Place the three numbers into the gaps on each line so that all seven calculations work out:

  •  ◯+◯–◯  =  1
  •  ◯–◯÷◯  =  2
  •  ◯+◯–◯  =  3
  •  ◯×◯–◯  =  4
  •  ◯×◯–◯  =  7
  •  ◯+◯÷◯  =  8
  •  ◯+◯–◯  =  9

The 7puzzle Challenge

The playing board of the 7puzzle game is a 7-by-7 grid containing 49 different numbers, ranging from 2 up to 84.

The Bottom Left to Top Right diagonal of the playing board contains the following seven numbers:

3     9     25     27     33     64     81

For the final challenge of the year, use these seven numbers exactly once each, with + – × ÷ available to use in your calculation, to arrive at our favourite target number of 7.
