How to Choose Which Slot Machine to Play
Most players pick a machine because the graphics caught their eye, a friend recommended it, or they had a good session on it last time. Advantage players do not. Game selection is where AP edge begins — before a single spin is placed. The difference between a random walk across a casino floor and a systematic survey of that same floor can be the difference between a negative-expectation session and a positive one.
Why Most Players Select Machines the Wrong Way
Recreational players rely on a mix of aesthetics, superstition, and anecdote:
- They pick themes they find visually appealing
- They return to machines that paid them before — as if past results influence future spins
- They avoid machines that "just paid out," believing a machine goes cold after a jackpot
- They follow other players, assuming a crowd means a machine is hot
None of these approaches have any bearing on expected value. Each spin on a random-state machine is independent. The machine has no memory of prior sessions and no obligation to you based on previous play. Selecting by aesthetics is simply random selection with extra steps — and the same negative expectation.
The Core Principle: Game selection is only meaningful when a machine has state — accumulated progress toward a trigger, an elevated progressive, or a known pay table edge. On a fully random machine with no state, selection cannot produce an edge. AP strategy starts by identifying whether any state-based opportunity exists on the floor before deciding where to sit.
What NOT to Use When Choosing a Machine
Before covering the correct hierarchy, it is worth being explicit about the inputs that carry zero weight in AP game selection:
- Gut feeling or intuition: There is no intuition about a random number generator. Feeling lucky is not information.
- Recent payout history: A machine that just paid a jackpot is no more or less likely to pay again. A machine that has not paid in hours is no more "due." The gambler's fallacy is the belief that independent events influence each other.
- Machine placement myths: The idea that casinos position loose machines near entrances, bathroom corridors, or high-traffic areas to attract attention is a durable myth with no operational basis. RTP is set in software, not by floor position.
- Other players' behavior: A crowd at a machine means nothing about that machine's state or payout. Crowds form for visibility reasons, not because players have identified genuine edge.
- Machine age or wear: Newer machines are not tighter; older machines are not looser. Hardware age has no relationship to RTP configuration.
The AP Machine Selection Hierarchy
When surveying a floor, evaluate opportunities in this order of priority:
1. Must-Hit-By Machines Near Their Trigger Threshold
A must-hit-by (MHB) machine guarantees a jackpot payout before a stated dollar amount — e.g., "Must Hit By $50." When the meter sits at $48.75, you are playing a machine that will pay out within a small, bounded window of play. The closer the meter is to its maximum, the higher the probability that your session captures that payout. This is the clearest positive-EV opportunity on most casino floors and the first thing to check.
2. Machines with Elevated Accumulated State
Some machines accumulate value over time in ways other than a progressive meter — filled bonus symbols, stacked wild positions, accumulated free spin credits, or community jackpot contributions that reset on payout. If a machine's accumulated state is significantly elevated above its average reset point, it represents positive value that a prior player left behind. Identifying these requires knowing the machine family well enough to recognize an elevated state when you see it.
3. Highest Denomination Available for Your Bankroll
When no state-based opportunity exists, denomination matters. Higher-denomination machines generally carry higher configured RTPs because the casino earns sufficient absolute margin per spin at a lower percentage. A dollar machine at 96% RTP is a better choice than a penny machine at 88% RTP if your bankroll can support 150+ spins at the dollar level. If it cannot, drop to the denomination that allows adequate session runway.
4. Video Poker at Full-Pay Tables
Full-pay Jacks or Better (9/6) returns 99.54% with correct strategy. Full-pay Deuces Wild returns over 100% with optimal play. When a full-pay table is available, video poker is almost always the highest base RTP option on the floor — often higher than any slot machine. The trade-off is that video poker requires known strategy; incorrect play collapses the return quickly. If you know the strategy charts, this is a top-tier selection.
5. Any Machine Where Free Play Is Being Deployed
Free play credits from casino promotions, mailers, or player rewards programs change the EV of any machine they are played on. When deploying free play, the selection priority shifts: play the highest-denomination machine your free play credit can support for a reasonable number of spins. The credit itself is equity — your job is to deploy it efficiently on a machine where denomination maximizes base RTP.
How to Survey a Casino Floor Quickly
A systematic floor survey takes under 10 minutes and dramatically improves session outcomes. The sequence:
- Scan progressive displays from the aisle. Walk the floor at a pace that lets you read progressive meters. You are looking for MHB machines that are near their maximum — a meter sitting at $47 on a "Must Hit By $50" machine is visible at a glance. This pass takes 3-4 minutes on most floors.
- Walk video poker banks and check pay tables. Video poker pay tables are printed on the machine screen. The key numbers to check: for Jacks or Better, the full-house and flush payouts per credit (9/6 is full-pay). For Deuces Wild, check the four-of-a-kind payout. A reduced-pay table is not worth your time over a slot machine with comparable RTP.
- Identify machine families you have guides for. If you have studied specific machine families, locate those on the floor and check their meter states. Knowing what an elevated state looks like on a machine you understand is a significant edge over a player who is seeing that machine for the first time.
- Default to denomination if nothing is elevated. If the survey reveals no MHB opportunities, no elevated state machines, and no full-pay video poker, select the highest denomination that your bankroll can sustain for 150+ spins and play.
Matching Machine to Bankroll
Even the best machine selection fails if you cannot sustain adequate session length. The rule of thumb: do not play a machine you cannot fund for a minimum of 150 spins at the required bet level. If a machine requires a $2.50 minimum bet, you need $375 in session bankroll before sitting down.
Why 150 spins? For most MHB and state-based opportunities, the positive event — the trigger, the bonus, the jackpot — occurs within a range of spins that requires sustained play to reach. Running out of bankroll at spin 80 on a +EV machine does not produce EV; it produces a loss. Session survival is the prerequisite for expected value realization.
- At $0.50/spin minimum: need $75 minimum session budget
- At $1.00/spin minimum: need $150 minimum session budget
- At $2.50/spin minimum: need $375 minimum session budget
- At $5.00/spin minimum: need $750 minimum session budget
If your session budget cannot support a given machine at 150 spins, that machine is not available to you regardless of how attractive the opportunity looks. Move down a denomination.
When Machine Selection Does Not Matter
It is important to be direct about this: if every machine on the floor is a fully random-state slot with no MHB mechanic, no accumulated bonus state, and no elevated progressive, machine selection cannot produce an edge. All machines with similar RTPs are equivalent in expectation.
In that scenario, the correct choice is straightforward: play the highest-denomination machine your bankroll supports, because denomination correlates with RTP configuration. Do not waste time searching for patterns in random outcomes or believing a cold-streak machine is about to turn. The correct action is to pick the best available RTP and accept the negative expectation that all random-state play carries.
AP play is not about finding magic on a machine with no state. It is about identifying the specific subset of machines and moments where positive expected value actually exists — and being in position when those opportunities appear.

How do you pick a slot machine?
Advantage players follow a priority hierarchy: first check for must-hit-by machines sitting near their trigger threshold, then look for machines with elevated accumulated state (filled bonus meters, stacked wilds, accumulated free spins). If no state-based opportunities exist, move to video poker and look for full-pay tables. Absent all of that, choose the highest denomination available for your bankroll, which typically carries the highest RTP on the floor. Random selection based on aesthetics or gut feeling is not a strategy — it is a coin flip with worse expected outcomes.
Do machine locations in a casino matter?
No. The widely repeated myth that casinos place loose machines near entrances, escalators, or high-traffic areas to attract attention is not supported by how modern casinos operate. Slot placement is driven by floor layout efficiency, theme clustering, and denomination zoning — not payout engineering by location. The RTP of a machine is set in its software configuration, not by where it sits on the floor. Choosing a machine because of its location is not an advantage play strategy.
Should you play slot machines near the entrance?
No. There is no evidence that machines near entrances pay better than machines elsewhere on the floor. This is one of the oldest slot myths and it persists because it is unfalsifiable to casual players — a good hit near the entrance confirms the belief; a bad run is forgotten. AP game selection is based on machine state and expected value, not geography.
How do AP players choose which slot machine to play?
AP players survey the floor systematically. Step one: scan progressive displays for must-hit-by machines approaching their maximum trigger amount — these are the highest-priority targets because they are guaranteed to pay before a known dollar level. Step two: walk video poker banks and check pay tables for full-pay configurations. Step three: identify machine families for which you have verified guides and check meter states. If nothing is elevated or near a trigger, the correct choice is the highest-denomination machine your bankroll can support for 150+ spins, which gives you the best available base RTP.
What is the best slot machine to play?
The best slot machine to play is one with a positive expected value — meaning your probability-weighted return exceeds your cost to play. In practice, this means a must-hit-by machine close to its trigger, a progressive at an elevated level above its historical average hit point, or a video poker machine with a full-pay table where correct strategy produces 99%+ RTP. If none of those exist on a given floor, there is no objectively best machine — all random-state slots with similar RTPs are equivalent, and the right move is the denomination that suits your bankroll.
