How do i cancel a draw offer?

I need to cancel a draw offer, I made it by mistake in a totally won game, the offer was going to do against the same opponent but in the other game, it would be a shame to tie a game where I have checkmate in two moves :(

Sorry for my english.

You can't.

Once a draw offer has been made, it is completely in the hands of the recipient. The player who offered has no say.

As others have said, you cannot rescind a draw offer after you have offered it. The recipient of the offer can simply decline, or just move a piece. Just hope they do that. haha

The above replies are all correct.  It's the same in an over-the-board tournament game.  Once a draw offer is made, it cannot be taken back.  Your opponent can accept or decline.

You can press the draw buttong, I think.

In my opinion this is a serious flaw often I just accidentally click it by accident. You should really make a cancel button.

You can't click it by accident. You should still have to confirm it.

No there is no confirmation for draw offers. Only for resignation is there a confirmation.

i accidentally double clicked to offer a draw when im up 3 full pieces in an end game..... 

yea happens sometimes too

Tragicomic

actually I just wanted to tease the opponent by offering a draw and quickly cancel it. turns out indeed you cannot cancel.

Yes

In which case, you could benefit from learning the rules that govern the game.
