Hotline Money is Provably Fair

Here the phrase has a testable meaning: the outcome of your round is fixed before you play it, and the game gives you a fingerprint of it in advance.

  1. Before the round: the seal

    The result is locked, and a fingerprint of that lock is shown to you while the outcome itself stays hidden. You hold the fingerprint from the start, and the later check depends on that.

  2. During the round: the outcome stays put

    You pick door A or B at each step, clear opponents, and either withdraw or go on to the boss. None of that alters what was sealed.

  3. After the round: the reveal

    The client releases the piece it held back. With that in hand you can recompute the fingerprint yourself and compare it against the one you were given before the first step.

Round ID
the reference for the round you are checking
Salt
the random string withheld until the close
Hash
the fingerprint shown before you played

All three appear on the client's own fairness screen, one set per round.

Who made it and what it offers

What 100HP builds into this game, and where to find it.

100HP is the studio behind Hotline Money. The rules inside the client list a 96% RTP, and the studio's game panel shows the same figure. The pre-bet screen shows the maximum multiplier per risk mode, x2031.63 on Easy and x54515.98 on Hard, and the Game limits panel lists the bet range and the payout cap. The Provably Fair round check is part of the game itself.

  • The round check belongs to the game and travels with it to every screen.
  • The rules state that a round's result is generated before it starts and does not depend on the player's actions.
  • Easy and Hard let you pick the risk level that suits your session.

Running the check yourself

Four steps, using only what the client shows you.

  1. Note the fingerprint before you play

    The client shows it on the fairness screen ahead of the round. Copy it or screenshot it. A check is only meaningful if you held the fingerprint before the outcome existed for you.

  2. Play the round out

    Pick doors, clear steps, then withdraw or reach the boss. The check works on any finished round, however it ended.

  3. Collect the released pieces

    At the close the fairness screen fills in the withheld string alongside the round's own reference. Those are the two halves you did not have before.

  4. Recompute and compare

    Feed the released string and the round reference through the same computation the game used, then compare the result with the fingerprint you kept. A match means the round you played is the round that was sealed.

Fairness questions

What readers ask about the figure and the round check.

What is the RTP of Hotline Money?
96%. The rules inside the 100HP client list it, and the studio’s game panel shows the same number. RTP only works over the long run, so a short session can come out much higher or lower.
What does a return-to-player figure describe?
It is a long-run statistical average across an enormous number of rounds, describing how much of the total staked is returned to players over that span. It speaks about the long run rather than one session or one run, so any single evening can land above or below it.
What does Provably Fair mean here?
It means the outcome of a round is committed to before you play, that you are given a fingerprint of that commitment up front, and that the pieces needed to re-check it are released once the round closes. The sealed answer holds all the way through, and you can check that yourself.
What are the Round ID, the Salt and the Hash for?
The Round ID names the round you are checking. The Salt is the random string the client withholds while you play. The Hash is the fingerprint you were shown before the first step. Recomputing from the released pieces and matching the original fingerprint is the whole check.
Can I verify a round after I have already closed the game?
Yes, as long as you kept the fingerprint you were shown at the start. So copy it before the round. The rest of the pieces are recorded against the round itself.
Does the check work the same on mobile?
Yes. Provably Fair verification belongs to the game itself, so an installed app, a home-screen icon and a desktop browser all expose the same fairness screen and the same three fields.
What is the maximum win in Hotline Money?
The pre-bet screen shows a maximum multiplier per risk mode: x2031.63 for Easy and x54515.98 for Hard. The demo’s Game limits panel lists payouts of up to 10 000 USD, and your casino lobby shows the cap for your account.
Does Easy or Hard change the RTP?
The rules give one figure, 96%, for the whole game. They also say that the higher risk level offers larger multipliers and a greater chance of defeat.
What does a fair round guarantee?
Fairness means the result was fixed before the round and can be proved afterwards. Any verified round, even one that closes on the second step, matches the fingerprint that was sealed for it.

The figure: 96%

The rules inside the 100HP client give Hotline Money a return to player of 96%, and the studio prints the same number on its own game panel. Those are the two places it appears, and both belong to the provider.

HotLine by Spribe and Hotline by NetEnt are different games with their own figures. The 96% on this page belongs to Hotline Money by 100HP.

What the number describes

A return figure is a long-run average. It describes what proportion of everything staked comes back to players across a span of rounds so large that no individual session registers on it. The 100HP rules say as much: RTP works over the long run, and in a short session the result can be much higher or lower.

The figure is therefore a long-run measure. The run you are about to take and the step you will stop on are yours to decide. Two players reading the same figure can have very different nights, and both nights sit comfortably inside it.

It is useful for comparing games and of little use as a guide to the next twenty minutes.

The figure in numbers

A 96% RTP means that across a very large number of rounds, 96 of every 100 units staked come back to players. Staking 1 000 USD in total over that span returns 960 USD on average. The rules give a single figure for the whole game, so the same 96% covers Easy and Hard alike, and it is the number to use when you compare Hotline Money with other instant games.

Limits that sit beside it

The demo’s Game limits panel lists a minimum bet of 0.1 USD, a maximum bet of 150 USD and a maximum payout of 10 000 USD. The pre-bet screen adds a top multiplier per mode: x2031.63 on Easy and x54515.98 on Hard. Your casino lobby lists the limits that apply to your account.

What this game includes

Hotline Money is Provably Fair, and the check belongs to the game itself. It has three stages and you can run it yourself.

Before you play, the outcome of the round is fixed and a fingerprint of it is shown to you. The rules put it the same way: the result is generated randomly before the round starts and does not depend on the player’s actions. You hold that fingerprint while the outcome stays hidden.

While you play, the sealed outcome stays fixed. You choose door A or door B at each step, clear opponents, and either press Withdraw or keep going towards the boss. None of it changes the answer that was locked before you started.

When the round closes, the client releases the string it withheld. With that string, the round’s own reference and the fingerprint you kept, you can recompute and compare.

A match confirms that the round you played is the round that was sealed, which is the whole purpose of the check. Take a round you can check and run it once.

What the check adds to a percentage

A long-run average describes a very large number of rounds, most of which you will never play. A round check describes the round you just played.

If a result surprises you, the check gives you a definite answer. Running it once is enough to see how it works.

The check is the same in a desktop browser, in an installed app on an Android handset, and behind a home-screen icon on an iPhone, because verification is part of the game client.

One habit worth forming

Copy the fingerprint before the round starts. Everything else is recorded against the round and will still be there afterwards, but the fingerprint only counts if you held it before the outcome. Screenshot it or note it down for the length of a session.

If a run then ends in a way you did not expect, you can check it and get a definite answer.

Risk, set your way

Easy and Hard form the risk dial. The in-game rules sum it up in one line: the higher risk level offers larger multipliers and a greater chance of defeat. The pre-bet screen shows the largest result each mode can reach, x2031.63 on Easy and x54515.98 on Hard, so you can pick the profile that fits the session.

The rest of the page describes the run and the parts that travel with every screen. To try the check, play a round and verify it yourself.
