Setting Up Tournament Blinds
A poker blinds timer tracks blind levels during tournament play. Standard structure: 15-20 minute levels, blinds double every 2-3 levels. For a 3-hour home game with 6 players, use 15-minute levels starting at 25/50, increasing to 50/100, 75/150, 100/200, etc. Add antes when blinds reach 4x starting level.

Balanced structure. Good mix of play and progression. Suitable for most home games and casinos.
Turbo (10 min)
Fast action. Higher variance, quicker finish. Good for casual games or when time is limited.
Frequently Asked Questions
How long should blind levels be?
For home games, 15-20 minutes per level is standard. Shorter levels (10-12 min) create faster, higher-variance games. Longer levels (25-30 min) allow more play and skill. Tournament length ≈ levels × level duration × 1.5.
When should I increase the blinds?
Blinds should roughly double every 2-3 levels. A common pattern: 25/50 → 50/100 → 75/150 → 100/200 → 150/300 → 200/400. This creates consistent pressure while allowing strategic play.
When should antes be added?
Add antes around level 4-5, typically at 10-20% of the big blind. Antes increase action by adding more to the pot preflop, making it more profitable to steal blinds.
How many levels for a home tournament?
Plan for 12-15 levels total. A 6-player tournament with 20-minute levels typically finishes in 3-4 hours. Add 1-2 levels if allowing rebuys during the first few levels.
What happens at level changes?
At level change: (1) Announce new blinds, (2) New blinds apply to the next hand dealt, (3) Color up small chips if needed, (4) If break scheduled, pause play. Give 1-minute warning before changes.
How this works
Calculations follow the published mathematics of the game — combinatorics for cards, probability theory for dice, and expected-value accounting for wagers. Results are verified against independent references (primarily Wizard of Odds). No calculation here is an opinion or recommendation; it is arithmetic applied to the rules of the game.
