How Degen Den Games Work

Degen Den offers three types of games: Live (stream-based betting), Real-Data (betting on verified real-world data), and Arcade (provably fair 1v1 vs the house). Each has its own mechanics and verification model.

Live Games — Stream-Based Betting

Live games use a real-time video stream. You watch the action unfold and bet on what will happen during a fixed round. Outcomes resolve from the actual stream—what you see is what settles your bet.

Deterministic Layout

Bubble positions are derived from the game pubkey before you bet. Same pubkey + refresh_index → same layout. We can't move targets.

On-Chain Pubkey

The game account exists on-chain before the round. Its pubkey seeds the layout. View any game on Solana Explorer.

Verify Anywhere

Call the positions API or recompute locally. Same inputs → same positions. Open algorithm—no trust required.

By Game

Target Splash

Target Splash is our flagship live game. A live video feed shows fish swimming around colored bubbles. Your job: predict which bubble (if any) will be popped during the round.

How a round works

30-second betting window — Place your bet before the round starts.
Colored bubbles — Red, Green, Blue, Yellow. A fifth option: None.
1 second to pop — A fish must stay inside a bubble for 1 full second to pop it. If the fish leaves early, progress deflates; re-entry continues from where it left off.
Multiple winners — Any popped bubble pays. Bet "None" only wins when zero bubbles are popped.

Multipliers

Red 1.5× · Green 4× · Blue 7× · Yellow 15× · None 1.2×. Fixed bet sizes: 0.05–1 SOL.

Resolution

The stream is processed in real time. When a bubble is popped (fish holds for 1s), that outcome is recorded. Round ends, winners are paid instantly on-chain.

Provably fair

Hash: SHA-256(pubkey + ":" + refresh_index) seeds the bubble layout. Positions are derived before the round—we can't move bubbles after you bet.

How Target Splash Fairness Works

Bubble positions are locked before you bet. The game account exists on-chain before the round; its pubkey plus a refresh index seeds the layout. Same pubkey + refresh_index → same positions. Anyone can verify.

Game created (before any bets)

The game account is created on-chain. Its pubkey is fixed and public. The position seed is SHA-256(pubkey + ":" + refresh_index). The first 8 bytes seed a PRNG; each of the 4 bubbles gets (x, y) from uniform draws. Layout is deterministic—no server can change it.

Bet

You bet during the 30-second window. The pubkey is on-chain; positions are derived from it. We can't adjust bubble locations based on your choices.

Verify

Anyone can call the positions API with the game pubkey and refresh_index, or recompute locally. Same inputs → same layout. The pubkey is public; no reveal step—the "commitment" is the game account itself.

Why "Live"?

Live games are driven by a live video feed. There's no pre-recorded data or simulated outcome—you're betting on what happens in real time. Target Splash uses IVS (Interactive Video Service) for low-latency streaming.

FAQ

Can Degen Den move the bubbles after I bet?

No. Positions are derived from the game pubkey and refresh_index. The pubkey is on-chain before the round. Same inputs always produce the same layout.

How do I verify the positions?

Call GET /api/target-splash/positions with the game pubkey and refresh_index, or run the algorithm locally. The formula is open source—same pubkey + refresh_index → same (x, y) for each bubble.
