Topic L-Game
  The L-game is an amazingly simple game, which was introduced by Edward de Bono in 1968 in his book "Learn to think in 15 days". Back in my studies and adolescence, this encouraged me to think outside the box (at least I tried).

Just give it a try - it's still fun (especially if you follow the winning strategy).
