At the table

Hole cards: The two private cards dealt to you.
Board / community cards: Shared cards everyone can use: the flop (3), the turn (4th) and the river (5th).
Preflop: Before any community card is dealt.
Flop / Turn / River: The board after 3, 4 and 5 community cards.
Showdown: When remaining players reveal hands and the best five-card hand wins.
Opponents: How many other players are still contesting the pot.

Equity: Your share of the pot expressed as a percentage — how often this hand wins at showdown if all remaining cards are dealt out.
Raw win probability: Equity measured against opponents holding completely random hands, with no assumption about how they play.
Adjusted equity: Raw equity scaled by a positional range factor, to approximate opponents playing tighter from early seats and wider from late seats.
Range factor: The multiplier applied to raw equity for your seat. Below 1.00 tightens the estimate, above 1.00 loosens it.
Tie probability: How often the hand splits the pot instead of winning outright.
Pot odds: The price of a call compared with the size of the pot you can win.
Break-even equity: The minimum equity that makes a call profitable: call amount divided by (pot + call). Above it, calling makes money over time.
Exact equity: A number produced by counting every possibility rather than sampling. Heads-up preflop spots read a precomputed 169-hand table, and heads-up spots with a flop, turn or river enumerate every opponent holding and runout.
Monte Carlo simulation: The sampling fallback used only for multiway spots, where full enumeration is too large: thousands of random runouts are dealt and averaged, landing within roughly ±1 percentage point at 8,000 runouts.
Trials / combinations: How much work produced the number: combinations counted on an exact path, or runouts dealt on the sampling path.

Round: A training session of 10 hands at one fixed difficulty.
Tolerance: How far your answer can be from the true equity and still count as correct.
Streak: Consecutive correct answers; it resets on any miss or timeout.
Timeout: A hand where the clock expired before you answered. Counts as a miss.
Score: Correct answers as a percentage of the hands in the round.
Avg error: Average distance, in percentage points, between your answers and the true equity.

Session: One logged visit to a table: a date, a buy-in and a cash-out.
Buy-in: The money you put on the table for that session.
Cash-out: The money you left the table with.
Net / profit: Cash-out minus buy-in for a session.
Cumulative profit: Running total of every session net, in date order — the line on the chart.
Win rate: Share of sessions that finished with a positive net.
ROI: Total profit divided by total buy-ins, as a percentage.
