Mechanics, in detail

How Hotline Money works

The mechanics in detail: the 30 opponents and the boss, what Easy and Hard change, what Autobet and Turbo do to a round, and how a finished round gets checked.

Hotline Money is an instant game from 100HP built on steps, so this page covers steps, paths and the boss rather than reels, paylines or symbol combinations. Titles of similar name from Spribe, NetEnt and Apollo Games are different games and sit outside this page.

The order of operations

A round always runs in this order.

  1. Before the round: risk

    Risk mode is selected on the pre-bet screen. Easy shows a maximum of x2031.63 and Hard a maximum of x54515.98. The stake is set on the same screen.

  2. At every step: the path

    You pick attack path A or attack path B, and the agent moves. The choice is offered again on every step.

  3. Through the run: the step

    Each cleared step raises the multiplier and adds one to a counter that runs from 0/30 to 30/30.

  4. At any live moment: the exit

    Withdraw is available from step one and remains so. Taking another step means passing on it.

  5. At the end: the boss

    Clear all 30 opponents and you meet the boss, which the splash screen names as the goal.

Each part, and what it is for

Six features make up the whole game, all inside the base round.

Step progression

The loop. A run is a chain of up to 30 steps. On Easy, the first five pay x1.04, x1.13, x1.24, x1.36 and x1.49.

The loop itself, not a bonus you trigger.

Attack path A or path B

The branch. Two doors are offered at every step, and you choose one before the agent moves.

Chosen again each time.

Boss fight

The objective. A run ends at the boss, so every step can be measured against a fixed end point.

Waiting at the close of the floor sequence.

Mid-run withdraw

The exit. Withdraw is live from the first step and pays the multiplier on screen.

Live from step one.

Risk modes

The dial. Easy or Hard, set up front. It is the nearest thing here to a difficulty selection, so check it before every round.

Selected before the first bet.

Autobet and turbo

The pacing toggles. Autobet hands a stretch of rounds to the client, and Turbo shortens the one in front of you. Decide your stake and exit before you switch either on.

Player-selected before or during play.

Provably Fair, done properly

Provably Fair on this game is a procedure with inputs and an output you can compare. It has four stages.

  1. A commitment comes first

    Before a round is played the client exposes a hash, a fingerprint of the outcome data, shown while the outcome is still unknown to you.

  2. You play the round

    The run happens normally. The fairness mechanism leaves the way you choose a path or take the exit untouched.

  3. The client reveals the inputs

    Once the round closes, the fairness screen shows the Round ID, the Salt and the Hash together.

  4. You reproduce the result

    Feed them back through the provider's verification and the outcome rebuilds itself. Matching output means the commitment made up front was the one that governed it.

Round ID
identifies the exact round under examination
Salt
the random string folded into the seed
Hash
the fingerprint committed ahead of play

You can check any round you choose, after the fact and on your own.

Questions about the mechanics

What happens at the boss?
The boss is the finale of a run and comes after the thirtieth opponent. The splash screen names it as the goal: defeat the boss, collect the prize, save the girl.
What do the two risk modes change?
The ceiling and the odds. The pre-bet screen shows x2031.63 for Easy and x54515.98 for Hard, and the rules say the higher risk level offers larger multipliers and a greater chance of defeat. Risk is selected there, before the round is started.
What is the practical difference between autobet and turbo?
Autobet works across rounds. It runs a number of rounds you set, collects each one at a step you set, and picks the path at random every step. Turbo works within a round by compressing the time it takes to resolve.
Is one attack path safer than the other?
Both paths carry the same weight. The 100HP rules say the result of a round is generated randomly before it starts and does not depend on the player’s actions. A and B are offered on each step and both lead towards the same boss.
What do the Live, My and Top tabs show?
They sit under the betting panel. Live lists bets as other players place them, My holds your own bet and withdrawal history, and Top ranks other players’ wins by amount and by multiplier over several time ranges.
How do I verify a round?
Open the fairness screen after the round closes and take the Round ID, the Salt and the Hash. Running those three values through the provider’s Provably Fair check rebuilds the outcome, and a match confirms the commitment shown beforehand governed it.
Is the cash-out available at every point in a run?
Yes. It is available from step one and stays live while the run is active, so every further step is a decision not to take the money yet.
Do I need an account to see how it plays?
The provider demo loads on this page and starts straight away. An account is needed only to play for real money.

Theory ends here

A game with a middle

In most gambling formats you place a stake and the machine resolves it at once. Hotline Money adds up to 30 steps between the stake and the result.

At every step you hold a multiplier you could keep. Each time you advance, you pass on Withdraw, and that repeats until you stop, a step fails, or you reach the boss.

Risk: Easy or Hard

Risk mode is chosen on the pre-bet screen, before the round starts. There are two modes, and the screen prints the maximum multiplier for each: x2031.63 on Easy and x54515.98 on Hard. The stake stepper and its chips for 1, 2, 5 and 10 are on the same screen.

Check the mode on the pre-bet screen at the start of each session, before the first run, so the round is played at the risk level you meant to choose.

The two attack paths

Path A and path B are offered on each step. You pick one, the agent moves, and the step clears or the round ends.

It is tempting to look for a dominant path, and the 100HP rules settle it: the result of a round is generated before it starts and does not depend on the player’s actions. What you can plan is how far you intend to go, since a player leaving mid-run and a player aiming for the boss need different stopping rules.

To find your own stopping step, take a few runs and note where you start to hesitate.

The boss, and the shape it gives the run

The sequence ends at a boss after 30 opponents, and a counter on the field shows how many you have cleared.

Because the run has a fixed end, every step can be measured against it. At 5/30 or 20/30 you know how far the boss is, which makes the decision to withdraw easier to reason about.

Withdraw

The cash-out is available from the first step and stays live while the run is active. After every cleared step you either press it or pick another door.

A session runs best when the exit plan stays the same in the middle of a good run. The decision made before any stake is down is the better one, so make it now, then start a round and hold to it.

Tempo: what Autobet and Turbo change

Autobet hands a stretch of rounds to the client. In the Auto Play window you choose an Auto Collect step and a number of rounds; the client then picks the path at random every step and collects when it reaches your step. A step that does not clear before then closes that round. Stopping Auto Play mid-round pauses it at the current step, and you can collect or carry on by hand. Turbo compresses the round in front of you. Both are toggles beside the stake controls, and neither changes the steps of a run.

What they remove is the pause. In a slow round there is a gap in which a person reconsiders, and both tools shorten it. So give Autobet a round count and give Turbo an exit rule before you switch them on.

The panels under the stake

Below the betting panel the client keeps three tabs. Live shows bets as other players place them. My keeps your own bet and withdrawal history. Top ranks other players’ wins by amount and by multiplier over several time ranges. 100HP presents this as the game’s leaderboard.

What Provably Fair buys you

Verification here is a procedure you can run. A hash is committed before the round. The round is played. The Round ID, the Salt and the Hash are then shown together on the fairness screen, and running them back through the provider’s check reproduces the result.

Run it once on a low-stakes round, so you know how it works.

Protection inside the rules

The rules also look after the round itself. Should the game software or hardware malfunction, the affected bets and payouts are cancelled and each player’s stake comes back within one hour. The rules recommend a stable internet connection, which keeps every round running through to its result.

Where to take this next

The parts list is short: Easy or Hard on the pre-bet screen, a choice of A or B every step, Withdraw beside every step, a boss after 30 opponents, two pacing toggles, and a fairness check afterwards. Rehearse in the demo on this page until you know where the controls are, then play Hotline Money for real, where the cash-out has weight behind it.
