Time to play games

Recently, the match between AlphaGo and Lee Sedol captured the attention of both the general public as well as the experts in AI, math and CS.

it’s time to try some gaming stuff for the Math Olympiads also. Take a break and try this:

A 10 x 10 checkerboard has every field colored in one of 15 given colours, such that each colour is used for at least 6 squares. Prove that there are three identically coloured, equally-distanced fields on the same row or columns. (IMAR Test, 2004).

More fun on the way!
