Here's a Pete Winkler classic:

You are playing a game against your adversary Bob. There are four indistinguishable coins on a tray, say in positions North, West, South, and East, each starting as either heads or tails according to Bob's liking. Bob can always see the tray, and you never can. A single turn consists of the following:

1. You ask Bob to flip any number of coins by referring to their position.

2. Bob rotates the tray to his liking (you do not get to know how the tray is being rotated, and he must rotate it by a multiple of 90°).

You win the game if you make all of the coins heads after finitely many turns, and Bob wins if you give up. There is a strategy that guarantees your victory. What is it?

Example and bonus question below the cut.

Example:

Maybe Bob chooses the following initial position:

H

T T

H.

You ask Bob to flip North and East, so the position becomes

T

T H

H.

Then Bob rotates the tray 90° to the right and the position becomes

T

H T

H.

It is now your turn again, and the game continues. At no point could you see anything on the tray, and you don't know how much Bob rotated it - for all you know, he could have not rotated it at all!

Bonus question: If there are only three coins, Bob has a winning strategy. What is it?
