🎲 Craps Odds & House Edge Reference
Craps is one of the only casino games where the house edge can be driven almost to 0% by combining Pass Line bets with Odds bets. The Odds bet has literally zero house edge.
💡 Strategy: Stick to Pass Line + Come bets with max Odds for the best possible return. Avoid all Proposition bets entirely.
🔴 European Roulette Odds Breakdown
Torn uses European Roulette (Single Zero). The house edge is a constant 2.70% on almost every bet — your choice of bet only affects volatility, not the expected return.
💡 Strategy: The house edge is identical regardless of bet. Bet Even-Money (Red/Black) for the slowest bankroll drain and most playtime per dollar.

Slot machines are pure RNG with no player input or strategy. Torn's exact Return to Player (RTP) is hidden, but standard casino slots range between 90–95%.
If you need to grind casino merits, slots are the fastest way to rack up play counts per dollar. Bet the minimum amount possible to maximize merit count while minimizing total cash burned. Don't expect to profit — budget only what you're happy to lose.
