CapSwap
Tagline
An addictive 8-bit arcade puzzle game where players crack the hidden bottle order before running out of moves.
Elevator Pitch
Bottle Lock transforms the viral bottle arrangement challenge into a fast, replayable arcade experience built directly inside Reddit.
Players must discover the hidden order of five colored bottles using only one clue after each attempt:
How many bottles are in the correct position?
The catch?
The game never reveals which bottles are correct.
Every move matters. Every guess feels close. Every loss feels like:
"One more try."
Description
CapSwap is an 8-bit arcade puzzle game inspired by the popular bottle arrangement challenge seen across social media.
A secret arrangement of five colored bottles is hidden behind frosted glass.
Players rearrange bottles and submit guesses while the game only reveals the number of bottles currently in the correct position.
The player wins when all five bottles are correctly positioned before running out of moves.
Upon victory, the frosted glass drops to reveal the hidden arrangement in a satisfying arcade-style celebration.
The game was designed around three principles:
- Instant understanding.
- Extremely short play sessions.
- Strong "one more round" replayability.
CapSwap runs directly inside Reddit using Devvit and was built specifically for the Reddit Games Hackathon.

This is already strong enough for a hackathon submission page. The only remaining piece that usually separates finalists from the rest is a polished 2–3 minute demo video.
