When you start playing tournaments or tracking results, the biggest hurdle is often the jargon. This glossary is grouped into four themes, with a sentence or two of plain explanation for each term. Where a term deserves more, a link to the full guide is included.

Entry and fees

Buy-in
What you pay to enter an event. Usually listed as "$100 + $12", where the first part goes to the prize pool and the second is the fee.
Fee
The amount the organiser keeps, which never enters the prize pool. Its share of the total price decides how much better than average you must be to break even — see the true cost of a tournament.
Re-entry
Registering again after busting, with a new starting stack and a new seat. Each one is a separate cost.
Rebuy
Buying another stack during a set period when your chips are below a threshold, without changing seats.
Add-on
An extra stack available at a set point, usually the end of the rebuy period, whatever your chip count.
Bullet
Slang for one entry. "I fired three bullets" means you entered three times.
Freezeout
An event with no re-entry. When your chips are gone, you are out.
Late registration
The period after the start during which you can still enter, usually given in levels.
Satellite
A qualifier whose prize is a seat in a bigger event instead of cash.
Guarantee (GTD)
The minimum prize pool the organiser promises.
Overlay
The shortfall the organiser covers when entries do not reach the guarantee. For players it amounts to free extra prize money.

During play

Blinds
The forced small blind and big blind on every hand, which rise with each level.
Ante
Extra chips put into the pot before each hand. With a "big blind ante", the big blind pays the whole table's ante at once.
Level
A period during which the blinds stay the same, for example 20 minutes.
Starting stack
The chips each player receives at the start.
Big blinds (BB)
Stack size expressed as a number of big blinds. This reflects your real room to manoeuvre far better than the raw chip count.
Structure
The full plan of starting stack, blind levels and level length. See how to design a blind structure.
Turbo
An event with short levels: faster and more volatile.
Deep stack
An event with a deep start, usually 200 big blinds or more.
Bounty / Knockout
Part of each buy-in becomes a bounty on that player, paid immediately to whoever eliminates them.
Colour-up
Exchanging small-denomination chips that are no longer needed for larger ones.
Chip leader
The player with the most chips at that moment.
Day 1 flights
Large events split the first day into several sessions (1A, 1B and so on), with survivors combining on Day 2.

Prizes and places

In the money (ITM)
The finishing places that are paid, usually 10% to 15% of the field.
Bubble
The stage when one more elimination brings everyone into the money. The last player out before the money is said to "bubble".
Min-cash
The smallest prize, for just making the money — usually 1.5 to 2 times the buy-in.
Final table
The stage when only one table of players remains. Prize jumps become large from here.
Payout structure
The table showing what share of the prize pool each place receives.
Deal / Chop
An agreement among the remaining players to divide the remaining prize money instead of playing to the end.
ICM (Independent Chip Model)
A model that converts chip stacks into expected prize money, often used for deals and bubble decisions. Its central idea: in a tournament, chips are not worth a constant amount, so doubling your stack does not double your expected prize.

Tracking and statistics

Bankroll
Money set aside only for playing, separate from living costs. See tournament bankroll management.
ROI (return on investment)
(Total prizes − total cost) ÷ total cost. See how to calculate poker ROI.
ITM rate
Cashes ÷ entries. See ITM vs ROI.
Hourly rate
Net profit ÷ total hours. See how to calculate your hourly rate.
Variance
How far short-term results stray from the long-term average. See variance and sample size.
Sample size
The number of events you have played. The more there are, the more your statistics can be trusted.
Downswing
A stretch during which your bankroll falls from a peak. A normal expression of variance.
Shot
An occasional event above your usual level.
Staking
Someone else funding part or all of your entry in return for an agreed share of any prize. See staking and team profit splits.
Markup
The multiple above cost at which shares are sold. At a markup of 1.2, 10% of your action costs 12% of the entry.
Makeup
In a long-term staking deal, accumulated losses that must be cleared before later profits are shared.
Tilt
A state in which emotion degrades your decisions. See tilt control and stop-loss rules.
