UPDATE: This offer should be live now and should appear at checkout when you add an original Grand Slam to your order!
Denny’s is bringing back their fan-favorite Grand Slam Giveaway for the fall championship series! When a player hits a Grand Slam during the series (scheduled for October 24–November 1, 2025), Denny’s Rewards Members will score a free Original Grand Slam.
To qualify, you’ll need to have a Denny’s Rewards account — if a Grand Slam happens, the offer will automatically appear in your account and can be redeemed November 3–10 at participating locations.
Limit one per member. Offer valid only if a Grand Slam Hit occurs during the championship series.
