you should compare it with a game whose rules you don't know, being able only to understand your score. like trying to play spider solitaire on windows without knowing how the game works (it allows you to undo your moves).
notice that in your example of solitaire, knowing the values of hidden cards really changes the nature of the game and makes playing the game much less strategic
It is clearly an April Fool's hack.
This is from the paper. "I tried again, and it was a huge breakthrough: Mario jumped up to get all the coins, and then almost immediately jumped back down to continue the level! On his fi rst try he beat 1-2 and then immediately jumped in the pit at the beginning of 1-3 just as I was starting to feel suuuuuper smart (Figure 7). On a scale of OMFG to WTFLOL I was like whaaaaaaat?"
