An apparatus used by bingo players as a reminder of the winning bingo square combinations established at the start of the game. The apparatus includes a small stand placeable on a table surface in front of a bingo player. A number of small informational panels are pivotably supported on the stand so that either the front face or the rear face of each panel can be seen by the player. Winning bingo square information appears on the front face of each panel; the rear face of each panel is left blank. The player can selectively adjust the different panels so that he/she is continually made aware of the potential winning square combinations in effect for the game being played.

Why it's free to use
- Filed August 14, 1992. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended August 14, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 14, 2014.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
