Turn Any Bottle Into The Party's Main Event
Balance color matched cards higher and higher until someone finally knocks the tower down. Works with whatever bottle's already on the table.
Same Three Games. Every Single Hangout.
You already know the drill. Someone digs out the same deck of cards, or worse, a board game that takes fifteen minutes just to set up. Ten minutes in, half the group is back on their phones and the night loses its spark.
GravityStack skips all of that. Clip it onto any bottle that's already in your hand and you're playing before anyone's even reached for their phone.
How It Actually Works
Clip it onto any bottle
Beer, soda, seltzer, water. If it's got a cap, the magnetic disc goes right on.
Balance color matched cards
Each color has to touch its match as the tower grows outward. Wild cards go anywhere, for better or worse.
Don't be the one who knocks it down
As the tower grows taller, one wrong move brings the whole thing crashing. Everyone's watching to see whose hand shakes first.

Questions Before You Play
Does this actually work on any bottle?
Yes. The magnetic disc attaches to the cap of pretty much anything, beer bottles, soda, seltzer, water. If it screws on, GravityStack works on it.
How long does a round actually take?
Most rounds run 5 to 15 minutes depending on how careful your group is. Long enough to build real tension, short enough to play again immediately after someone knocks it down.
What if it's just two of us, or a huge group?
GravityStack is built for 2 to 8 players, so it works for a quiet night in just as well as a full backyard hangout.
Will a spilled drink ruin the cards?
The cards are waterproof, so a splash off the bottle or a spilled drink wipes right off without warping the cards.
Is this a one time novelty or something we'll keep playing?
Every round builds differently depending on how the tower grows, so no two games play out the same way. That's the part that keeps people playing round after round.
How is this different from Jenga?
Jenga is one tower everyone slowly takes apart. GravityStack is a tower everyone builds together, outward from a bottle, so the tension comes from adding instead of removing.
