Flat Betting vs 1-3-2-6: Which Bankroll Style Fits Online Play in 2025?
Simple sizing beats hunches: short blocks, fixed units and clear exits for roulette, crash & slots

Most casino mistakes aren’t math—They’re pacing. The cleanest fix is picking a sizing style you can execute. In 2025 the two most practical options are Flat Betting (same unit every round) and the streak-friendly 1-3-2-6 ladder (reset on loss, cap after four wins). Neither beats house edge—but both can protect mood, time and bonus progress when paired with short sessions.
Flat Betting: calm data, steady progress
Use a fixed unit of 1–2% bankroll. It’s ideal for missions, wagering and low-volatility titles. Your graph is smoother, logs are cleaner, and “just one more raise” never happens—because it’s not allowed.
1-3-2-6: capture runs without snowballing risk
- Start at 1u; after a win go 3u → 2u → 6u; any loss resets to 1u.
- Great for streaky tables or mini-tournaments; terrible if you ignore the reset.
- Cap the ladder: stop after the 6u hit—bank and go back to base.
Session design that makes either work
- Blocks: 12–18 minutes with a timer, then 2–3 minutes off-screen.
- Stops: cash out at +2 units or halt at −3 from the session peak.
- Log: game, unit, result, mood (1–5). Data > vibes.
Bottom line: choose one style per block. Flat for discipline and missions; 1-3-2-6 when you want a contained shot at hot runs. The win isn’t a system—it’s the structure around it.
