New version – 11/16/2016
Hi,
These {Admin Edit} from Rovio understood that they made some {Admin Edit} with the previous updates (obtaining of plans easily in boxes). They thus decided to change mode of progress for the releasing of the new karts.
You will need between 200, 500, 800 or 1.000 plans to unlock a kart. The total asked for all to unlock them is 11.700.
Know that after the update, your current plans increase tenfold. Thus if I have an advice, it is to use full of tickets to open boxes to tools to reach 1.170 plans. After the update you will have 11.700.
Otherwise the old karts can be again improved.
Not still tested the races.
