A game about weathermen where the object is to predict the correct weather. Doing this correctly moves a frog up a ladder -- the player with the highest frog at game end is the winner. Play revolves around 36 weather cards which have different weather symbols 1, 2 or 3 white or black clouds. The board is a 4x4 grid with pictures of different houses along the vertical and horizontal planes, the higher the house, the better the initial weather. The game starts with weather tiles being randomly placed face down onto the grid. The tiles stay that way for much of the game, which means Donnerwetter has a memory element. The idea is to place your prediction marker and trying to change the weather tiles to match. The rest of the game is spent moving and laying tiles with limited intelligence, trying to get your predictions to come right.Designed for ages Ages 10 and up. - BoardGameGeek
