Modbury School was the only school to send in solutions to Got It!

For the game with a target of 23 and numbers 1, 2, 3 and 4 to choose from, Joe and Benjamin said:

You start with 3 and then you go 8 after the computer's go, then to 13 after the computer's go, then 18 after the computer's go, then 23 after the computer's go.
On 22 you do the same but minus 1:  7 12 17 22

In Got It with the three numbers (1, 2 and 3 to choose from) you have to get 15 and 19 then you'll definitely win.
If you're on the two numbers (1 and 2 to choose from) you have to get 17 and 20 then you will also win again.

Thank you all who were involved at Modbury, we hope to hear from you again.
