🎲Roo Lottery
The Roo Lottery is Sniperoo’s high-energy, high-reward minigame that lets you turn your Roobits or SOL into a shot at winning the entire prize pool.
Whether you’re betting spare Roobits from your trading activity or dropping direct SOL into the pot, every entry increases your chance to walk away with the winnings.
How It Works
The Roo Lottery runs in rounds. Each round has:
A live countdown timer
A growing prize pool (displayed in SOL and USD)
Real-time tracking of your entries, chances, and potential payout
When the timer hits zero, the system selects one winner based on contribution weight. The more you contribute, the higher your odds.
Entry Options
You can join using:
SOL – Directly from your available balance
Roobits – Converted automatically into SOL at a fixed rate of 100,000 Roobits = 1 SOL. Learn how to earn Roobits by visiting the the Roobits Page
Minimum bet amount is 0.001 SOL or 100 Roobits.
How to Play
To participate, you first need to decide whether you'll be betting with SOL or Roobits. You can either type in a custom value or use the quick-add buttons to increase your bet instantly.
To place your bet simply click the Place Bet button.
When you place your bet, your contribution is immediately added to the current round’s prize pool.
Your win probability updates in real time.
You can place multiple bets in the same round as they stack together, giving you a higher overall chance of winning.
As the countdown ticks toward zero, keep an eye on the prize pool and other players’ entries. The odds shift dynamically as new bets come in, so timing your entries can be part of the strategy.
When the round closes, the system randomly selects a winner based on each player’s weighted share of the pool.
If you win, your prize appears instantly on the results screen, and the reward is added automatically to your main wallet.
Winner Selection
What is Weight Your weight is your share of the total contributions in a round, expressed as a percentage. The higher your contribution, the more of the “winner selection range” you control.
How the Winner Is Chosen When a round ends, the platform generates a random number between 0 and 1. Every player’s weight is mapped to a portion of that range. The player whose range contains the random number is the winner.
Example
Player A contributes 2 SOL → covers range 0.0 to 0.2 (20% chance of winning)
Player B contributes 5 SOL → covers range 0.2 to 0.7 (50% chance of winning)
Player C contributes 3 SOL → covers range 0.7 to 1.0 (30% chance of winning)
If the random number is 0.65, it falls inside Player B’s range — they win the entire prize pool.
This system ensures full transparency: every entry increases your weight proportionally, and the winner is always picked based on actual contributions.
The Round Flow
The Roo Lottery moves through four key states, which you’ll see reflected in the interface:
Active Round – Place your bets with Roobits or SOL. Your current entries and win chance update instantly.
Round Closed – Timer hits zero. No more entries accepted.
Selecting Winner – The system generates a random value to determine the winner based on weighted ranges.
Winner Announced – The winning player’s name, avatar, win chance, and total SOL won are displayed.
Quick Tips
Keep an eye on late entries, as they can shift the odds fast.
Using Roobits you’ve earned from trading is a great way to play without touching your SOL balance.
If you’re going for the win, consider stacking multiple entries to push your chance % higher.
