Go back to the same board after losing the game?

Would be great to have an option to try the same board once again after losing the game. May be a possibility to undo all the way back to the beginning?

There is a "undo" button, to undo all the moves back to the beginning.

After losing the game, the undo button is blocked, isn't it? By the this yellow screen suggesting to start a new game or to view the stats, I think.

That's true - after losing the game, the undo button is blocked.

We will look into adding a "start again" and "undo" functionality, when the player loses. Nice idea.
