HiLo is not a card-counting game
Despite the name, current GWYF HiLo is a probability-slider game, not a card Higher/Lower game. Some older community guides describe a card-reading game. The extracted implementation uses a continuous Over/Under slider and a uniform random result.
- Choose the slider threshold
- Choose Under or Over
- The game draws a uniform random result
- The result either lands on your side or it does not
- The payout is calculated from that side’s probability
Under: win chance equals the slider value. Gross payout equals EstimatedValue divided by that chance.
Over: win chance equals 1 minus the slider value. Gross payout equals EstimatedValue divided by that chance.
Over and Under are the same bet at the same probability
A 20% Under and a 20% Over pay the same. Slider 20% Under and slider 80% Over are both a 20% side, so both pay 5× at packaged EstimatedValue 1.
A 10% side is a raw 10×
At packaged EstimatedValue 1, payout is 1 divided by the selected-side win chance. A 10% side pays 10×. That is one result, not a chain of wins.

Payout is EstimatedValue divided by the selected-side win chance. At the packaged value of 1, that is 1 divided by the win chance.
Risk presets
These set the selected-side win chance. Safe-ish still loses 40% of the time.
How HiLo actually works
One uniform result, compared with the slider you set.
Selected-side payout = EstimatedValue / selected-side probability.
There is no deck composition edge in the current implementation. The skill is the risk you choose, the bankroll you keep, the challenge you are finishing, and when a profit buff is active.
Probability to payout
Packaged EstimatedValue is 1, so payout is 1 divided by the win chance.
| Win chance | Payout | Loss chance | Gross EV |
|---|---|---|---|
| 60% | 1.667× | 40% | 100% |
| 50% | 2× | 50% | 100% |
| 40% | 2.5× | 60% | 100% |
| 25% | 4× | 75% | 100% |
| 20% | 5× | 80% | 100% |
| 10% | 10× | 90% | 100% |
| 5% | 20× | 95% | 100% |
Is there a best slider?
No. Every normal slider has the same baseline gross EV. Moving it changes variance, hit rate, payout size, challenge efficiency, and how hard a buff has to work.
Pulling the slider to 10% does not create a higher baseline EV. At packaged EstimatedValue 1, probability times payout stays about 100%.
| Goal | Slider direction |
|---|---|
| Protect bankroll | Higher win chance |
| Low variance | Near 50% or higher |
| Huge payout | Low win chance |
| Roll the Odds | Progress speed against bankroll |
| No Safe Rolls | A side that still finishes at 10× or more |
| Profit buffs | A higher win chance can still clear the raw payout bar |
Same EV, very different experience
Two sliders can share the same baseline gross EV and still feel nothing alike.
10% winning side
10× raw payout. About 90% of rounds miss. Large but rare wins, long losing stretches.
Both sit at about 100% baseline gross EV. The slider changes the path, not the baseline edge.

Roll the Odds
Profit a lot of money on HiLo on Floor 2.
Floor 2 HiLo. Cumulative positive casino profit of current quota × 50%. Reward: 9 Tickets. Configured Floor 2 pool share is about 11.11%.
The counter adds positive HiLo profit. It is not your final HiLo profit-and-loss, and a later loss does not subtract progress already counted.
Challenge progress and bankroll health are not the same thing.
On a $1,000,000 quota the target is $500,000 of positive HiLo profit. A +$200,000 round, a −$500,000 round, and a +$300,000 round still add $500,000 to the counter. The bankroll is still down $500,000 from the loss.
Required positive HiLo profit
$500,000
Roll the Odds strategy
The challenge never subtracts losses, so a lower win chance adds more expected positive progress per dollar. It also misses far more often. 10% is not always best.
At packaged EstimatedValue 1, expected positive progress per $1 wagered is 1 minus the win chance.
Conservative
Slowest progress, misses least
0.40 expected progress per $1. 40% miss.
Balanced
Middle of the range
0.50 expected progress per $1. 50% miss.
Aggressive
Faster progress, misses more
0.80 expected progress per $1. 80% miss.
Extreme
Fastest expected progress, misses most
0.90 expected progress per $1. 90% miss.

Faster expected progress
Lower the win chance. The counter rises faster per dollar, and you miss more rounds.
Better bankroll survival
Raise the win chance. Progress is slower and losses are less frequent.
Challenge progress and bankroll health are separate. A losing round adds nothing to the counter but still costs the bankroll.
No Safe Rolls
Win 10x on HiLo on Floor 3.
Floor 3 HiLo. One final payout of at least 10×. Reward: 12 Tickets.
Do I need 10 consecutive HiLo wins?
No. Current game data checks for a final payout of at least 10×.
With no profit buff and packaged EstimatedValue 1, a 10% winning side produces a raw 10× payout. The success chance of that one round is 10%.
The extracted challenge does not ask for 10 consecutive wins.
10× · 10%
Sets the selected side to a 10% win chance: a raw 10× with no profit buff.
10× slider calculator
Profit buffs scale only the profit above 1×. A smaller raw payout can still finish at 10×, so they let you pick a safer slider.
Required raw payout = 1 + 9 / profit factor. The highest usable win chance is EstimatedValue divided by that raw payout.

Where HiLo appears
First available on Floor 2. It also appears on Floors 3 and 4.
Floor 3’s No Safe Rolls challenge is itself proof that HiLo is not only a Floor 2 game.
Floor 1 does not include HiLo.
- Floor 2 · configured pool share about 11.11%
- Floor 3 · configured pool share about 9.09%
- Floor 4 · configured pool share about 6.25%
Items and buffs
Gambler’s Confidence, Tipsy, and Melody multiply the profit above 1×. They lower the raw payout you need for a 10× final result. They do not change the uniform draw.
Insurance returns part of a losing bet. That protects the bankroll. It does not turn a miss into the 10× payout No Safe Rolls checks.
The page does not restate the buff engine. A positive-profit factor is enough here.
Trying to replay a HiLo outcome?
The current odds model is uniform. Persistence and reload behavior is a separate implementation question. This page does not treat a reload as a guaranteed repeat of the same Over/Under result.

EstimatedValue and the EV proof
Version-sensitive
Calculations currently use packaged EstimatedValue = 1.0. If a later runtime value differs, these payouts scale with it.
The result is uniform. Under wins with probability p and pays EstimatedValue / p. Over wins with probability 1 − p and pays EstimatedValue / (1 − p). Either way, probability times payout equals EstimatedValue.
Packaged base bet inputs are $10 / $100. Live values may scale or be remotely configured. They are not permanent table limits.
HiLo questions
How does HiLo work in Gamble With Your Friends?
You set a slider threshold and choose Over or Under. The game draws a uniform random result. If it lands on your side, the payout is EstimatedValue divided by that side’s win chance.
Is HiLo a card game?
No. The current extracted implementation is not a card Higher/Lower. It is an Over/Under probability slider with a uniform result.
Do I need to count cards?
No. The current result is uniform. There is no deck composition edge to count.
What does the HiLo slider do?
It sets the threshold. Under wins with probability equal to the slider. Over wins with probability equal to 1 minus the slider.
Should I choose Over or Under?
Choose the side whose win chance you want. The same win chance pays the same amount.
Is Over better than Under?
No. At the same selected-side win chance they are the same bet. Slider 20% Under and slider 80% Over are both a 20% side.
What probability should I choose?
It depends on the goal. Higher win chance protects the bankroll. Lower win chance pays more and progresses Roll the Odds faster per dollar, while missing more often.
What slider gives 2×?
A 50% side. At packaged EstimatedValue 1, payout is 1 divided by the win chance.
What slider gives 5×?
A 20% side. Slider 20% Under and slider 80% Over are the same bet.
What slider gives 10×?
A 10% side with no profit buff. A profit buff lowers the raw payout you need.
What slider gives 20×?
A 5% side. Payout is 1 divided by the selected-side win chance at packaged EstimatedValue 1.
Is there a best HiLo slider?
There is no best slider for baseline EV. Every normal slider stays at about 100% baseline gross EV. The slider changes variance, hit rate, payout size, and challenge efficiency.
Does a lower win chance have better EV?
No. A lower win chance raises the payout, not the baseline expected value. Probability times payout stays about 100% at packaged EstimatedValue 1.
What is the HiLo RTP?
The packaged baseline gross return is 100% at EstimatedValue 1. Each round still wins or loses; the return is a probability-weighted figure, not a guarantee.
Why do all probabilities have the same baseline EV?
Because payout is EstimatedValue divided by the selected-side probability. Multiply that probability by the payout and the EstimatedValue cancels out.
What is Roll the Odds?
A Floor 2 HiLo challenge. Accumulate positive HiLo profit equal to half the current quota. The reward is 9 Tickets.
How much profit do I need for Roll the Odds?
Current quota × 50%. A $1,000,000 quota needs $500,000 of positive HiLo profit, not a fixed amount for every run.
Do losses reduce Roll the Odds progress?
No. The counter adds positive profit only. A losing round adds nothing and does not subtract progress already counted.
What probability is best for Roll the Odds?
A lower win chance adds more expected positive progress per dollar, because losses are ignored. It also misses more, so it risks the bankroll faster. There is a trade-off, not one answer.
Why can a risky slider progress Roll the Odds faster?
Expected positive progress per $1 is 1 minus the win chance at packaged EstimatedValue 1. Lowering the win chance raises that figure while raising the miss rate.
What is No Safe Rolls?
A Floor 3 HiLo challenge. Finish one round with a final payout of at least 10×. The reward is 12 Tickets.
Do I need 10 consecutive wins?
No. The extracted challenge checks one final payout of at least 10×, not a streak.
What probability gives a raw 10× payout?
A 10% winning side at packaged EstimatedValue 1. Choose 10% Under or slider 90% Over.
Do profit buffs help No Safe Rolls?
Yes. They scale profit above 1×, so the required raw payout drops from 10× toward 1 + 9 / factor. A 6× profit factor can clear 10× from a 40% side.
How does Gambler’s Confidence change the required slider?
It raises the positive-profit factor. A higher factor lowers the required raw payout and lets a higher win chance still finish at 10×.
Do profit buffs improve my winning probability?
No. They change settlement, not the uniform draw. A buff can let a safer slider qualify, but it does not make the random result more likely to land on your side.
Why does No Safe Rolls mention Dice?
Players reported an in-game description that said Dice. The Steam achievement and the extracted game-type requirement both say HiLo. The stored achievement key and asset name use Dice.
What Floors have HiLo?
Floors 2, 3, and 4. It is first available on Floor 2.
Why can’t I find HiLo on Floor 2?
Floor eligibility is not a guaranteed spawn. HiLo is in the Floor 2 pool, but the current layout may not generate it. Floor 1 never includes it.
Can I save scum HiLo?
Use the saves and RNG guide for reload behavior. This page does not treat a reload as a guaranteed repeat of the same result.
