Tengo

We invented this funny multiplayer puzzle game called Tengo.
Simple but surprisingly challenging though.
Well actually it can drive you mad!
Unless you become good at it.

The game is played on a square of 16 tiles. You will be given sixteen numbers to place on the tiles. Put the numbers in lines, in a way that each line adds up 10.
The lines can be horizontal, vertical and diagonal. There are four tiles that can be used as parking spaces. Notice that you don’t have to use all numbers.

Now let’s Tengo.
