Abstract

Abstract A practice board for contract bridge games comprising a sheet having indicia showing hands, cards to play, numbers of tricks won, bids, etc. of respective players thereon and arranged in accordance with a predetermined contract bridge game and a cover member overlying the sheet and having apertures formed therein corresponding to said indicia on the sheet and through which the indicia on each single trick can be seen. The predetermined or celebrated contract bridge game can be practiced by sliding the sheet downward relative to the cover member trick by trick to show the indicia on the succeeding trick until all the thirteen tricks are over. The lids are mounted over required apertures so that a user can see only his hand and the dummy, a card played by each player in turn and bids at each round of bidding. The practice board according to the invention is handy, simple in structure and may be manufactured at low cost.
