Like postage stamps and gold-plated Yahtzee dice, bingo cards may be used in lieu of legal tender. Cash in with today's Groupon: for $10, you get a $20 buy-in credit at B&G Bingo, in support of the Boys & Girls Clubs of Salem, Marion, and Polk Counties.

For 31 years, the Salem Boys & Girls Club has fueled its charitable efforts with funds harvested from beneficent big-winners at B&G Bingo. The Bingo house offers multiprogressive games with escalating jackpots and colorful markers that fuel spontaneous connect-the-dot duels. Paper packs of Bingo cards buy in between $5 and $10, while other games such as Sizzlers, Bonanza, Blackout, and the rhythmic spinoff game Ringo cost a little extra. Fourteen sessions are gleefully strewn throughout the week. This Groupon is not valid for late-night sessions, starting at 10:30 p.m., on Friday and Saturday nights.

B&G Bingo recently moved to a new facility, which features a full-service deli and a widely variegated lottery station where players may further push, pull, and braid their luck with scratch-off tickets. The game room, like an unused Bingo card, is clean, open, and convivial. Electronic Bingo packages are also available, ranging from a $21 to a $39 minimum.
