How was this a repetition?
Why was my game a draw?

A threefold repetition draw is the same position repeated 3 times (with the same color to move) on the chess board during one game.
It does not need to be the same moves played 3 times. Also note that it may be a lot of moves between the 3 repeated positions, even it was not the case in your game.
The 3 repeated positions is marked in the notation sheet.

It wasn't the case of insufficient material or no available moves or repetition. But the game ended draw in the middle of nowhere. Please help clarify.
