This test measures your brain's ability to plan ahead.<br>
A tree-shaped frame will appear on the screen with 9 numbered balls slotted onto the branches.<br>
Rearrange the balls so that they are slotted onto the branches in numerical order making as few moves as possible.<br>
You can only take balls that are not blocked in by another ball and you can only move one ball at a time.<br>
Green balls are in the right place and red balls are not. You may need to move both red and green balls to solve the problems in the minimum number of moves.<br>
Solve as many problems as you can in 3 minutes. <br>
