Long Or Short ($LOS)

1 Abstract

Long or Short ($LOS) is a skill-based crypto prediction game built on Solana. Players watch live crypto price charts and predict whether the price will go up (LONG) or down (SHORT) within 30 seconds.

The game launches in three phases:

No house edge. No hidden fees. Odds reflect true market probability.

2 The Game

2.1 Round Structure

• Each round lasts 30 seconds.
• First 10 seconds — betting window open.
• Last 20 seconds — chart continues, no new bets accepted.
• At second 30, the round closes and settles instantly.

2.2 How to Win

• At round start, the current price is recorded as the reference price.
• At round close, the final price is compared to the reference:

2.3 Dynamic Odds

Odds adjust in real time based on:

1. Price momentum over the last 60 seconds.
2. Move from reference — how far the price has drifted from the round start.
3. Time pressure — odds become more extreme as the round nears its close.

Odds range: 1.03x to 15x per side.

2.4 Markets

Initially supported pairs:

2.5 Player Identity

• Login via Phantom wallet on Solana.
• Wallet address = player identity.
• No email, no password, no KYC.
• Private keys never leave the player's wallet.

4.4 Leaderboard & Giveaways (Q2 2026)

5 Game Economics

5.1 Player vs. House

The game operates as a player-versus-house model. The house is the dev wallet.

Player bets X $LOS at odds O
    ↓
WIN  → Dev wallet pays X × O to the player
LOSE → Player's X $LOS goes to the dev wallet
TIE  → Player is refunded X $LOS

5.2 Why the Dev Wallet Holds a Large Supply

The dev wallet is the game bankroll — equivalent to the "house" in a casino. It holds a large $LOS supply for three reasons:

5.3 Transparent by Design

The dev wallet's holdings are publicly visible on the Pump.fun pool. Anyone can verify:

• How much $LOS the dev wallet holds.
• How it changes over time based on game outcomes.

No hidden supply. No locked allocations. Everything is on-chain.

5.4 Fair Odds

Odds reflect true market probability:

There is no artificial house edge. A perfectly neutral player base leaves the dev wallet roughly unchanged over time.

5.5 Exposure Cap

A maximum payout per round is enforced to prevent catastrophic losses. Excess bets above the cap are partially refunded. The cap value is published on the website.

6 Technology

6.1 Stack

6.2 Architecture

[Binance Feed] → [Game Server] → [WebSocket] → [Player]
                       ↓
                    [Redis]
                       ↓
                [Solana RPC] ↔ [Phantom Wallet]

The server relays prices, manages rounds, validates bets, and orchestrates settlements. Solana handles on-chain $LOS transfers starting Phase 3.

7 Fairness & Security

• No custody. Private keys never leave the player's Phantom wallet.
• Message-sign only. Login uses SIWS — no key exposure, no seed phrase.
• Live price feed. Prices sourced from Binance and independently verifiable.
• Server-authoritative. Odds and settlement computed server-side; clients only render.
• Betting window closes 20 seconds before settlement.
• One bet per player, per round, per market.
