How many outs do you have to the best hand?
An out is any card left in the deck that would give you the winning hand — e.g. a flush draw has 9 (the suit's nine remaining cards).
The math of drawing hands is easy once counting outs is a reflex. This trainer builds that reflex, one real hand at a time.
At the table you can't open a calculator — you glance at the board and your hand and the number has to be there. That only comes from reps. This trainer deals real draws and asks the one question that matters: how many cards win it for you? Get it fast and the rest of the math — your equity, whether the price is right — falls out of the rule of 2 and 4 in a second. It's the single most useful mental habit a developing player can build.
Every answer here shows you exactly which cards are the outs and turns them into your chance of hitting by the street — nine outs is about 35% by the river, eight is 31%, a gutshot's four is 16%. Once counting is automatic, price the spot with the outs calculator and the pot odds calculator, and the whole call-or-fold decision takes a heartbeat.
Read the spot, count the outs, learn the equity — repeat.
You get a real hand and flop (or turn) on the felt. Work out every card that would give you the winning hand.
Choose how many outs you have from the four options. Only clean outs — cards that actually make you best — count.
Every answer reveals which cards are the outs and your chance to hit by the river, so counting and the rule of 2 and 4 become second nature.
Fix A card that completes your straight but puts a flush on board isn't a clean out. Count only cards that make you the winner.
Fix Nine outs is ~35% with two cards to come but only ~20% with one. Always check whether you're on the flop or the turn before you price it.
Fix A flush draw plus a straight draw isn't 9 + 8 = 17 — the cards both draws share are counted once, so it's about 15.
Fix Outs tell you how often you hit, not whether to call. Compare your equity to the pot odds before you put chips in.
An out is any unseen card that gives you the best hand. A flush draw has nine outs (the remaining cards of your suit); an open-ended straight draw has eight. Only count clean outs — cards that actually make you the winner.
A fast way to turn outs into equity: multiply your outs by 2 for one card to come, or by 4 when you're all-in on the flop with two cards to come. Nine outs ≈ 18% for one card, ≈ 36% for two.
Every correct out count builds your score and streak and earns XP toward your rank; your best streak is saved on your device. Accuracy tracks how often you nail it across the session.
To drill the difference in odds. The same nine-out flush draw is about 35% to hit with two cards to come but only about 20% with just the river left — the trainer mixes both so you learn to check the street.
Yes. Every scenario is hand-picked so the number of clean outs is unambiguous, and the equity shown uses the exact probability (with the rule of 2 and 4 as the table-side shortcut).
