Slot machines are casino games controlled by random outcomes rather than player skill. Modern machines use digital reels, stored credits, betting lines, bonus features, and programmed payout rates.
Before play, Franz should establish:
Minimum and maximum wager
Number of active lines
Available credits
Whether the machine has a jackpot
Whether bonus rounds or free spins are available
Whether the machine is legal, private, or illegally modified
Players should choose their wager before each spin.
For ordinary play, roll 1d100 for each spin and apply the result below.

A payout includes the returned wager unless otherwise stated.
Example: A character wagers 10 GP and rolls 90. They receive 20 GP total.
This table represents an ordinary casino machine. Individual machines may use different payout tables through their item or POI records.
When a player rolls 100, Franz may resolve one of the following:
Award 25 times the wager
Trigger a bonus round
Award several free spins
Activate a progressive-jackpot chance
Produce a special result listed in the machine’s record
For a progressive jackpot, roll another 1d100:
01–85: Win 25 times the wager
86–97: Win 100 times the wager
98–99: Win 500 times the wager
100: Win the advertised progressive jackpot
Large winnings may trigger identification checks, tax records, machine inspection, surveillance review, and attention from casino management.
Franz should establish the actual jackpot amount before the spin when it could become important.
A player may increase the wager by activating more paylines or increasing the amount bet on each line.
Larger wagers increase both possible payouts and losses. They do not improve the chance of winning unless the specific machine states otherwise.
For quick play, treat the listed wager as the total amount risked on the spin rather than resolving every individual payline.
A machine may require a maximum wager to qualify for its largest jackpot. This condition must be visible or explained before the player spins.
Slot machines favor the casino over repeated play.
Normal slot play requires no skill check. Intelligence may help a character:
Understand the payout table
Recognize misleading jackpot advertising
Compare machines
Identify unusually poor payout rules
Notice a machine behaving incorrectly
Suggested checks include:
DC 10: Understand the displayed wager and payout
DC 12: Compare two ordinary machines
DC 15: Recognize suspicious or misleading settings
DC 18: Identify evidence of mechanical or software manipulation
A successful check provides information. It does not change a fair random result.
Repeated spins should not become an unlimited source of money. Over time, the house advantage normally causes losses.
Machines may accept:
Casino chips
Cash
Player cards
Digital casino accounts
Printed vouchers
A cash-out voucher may contain:
Amount
Machine number
Time
Casino location
Transaction code
Large cash-outs may require identification or review at the casino cage.
Stolen vouchers may be traceable through cameras, player accounts, timestamps, or machine records.
Possible methods include:
Counterfeit vouchers
Stolen player cards
Hacked casino accounts
Altered machine software
Insider access
False maintenance credentials
Physical tampering
Manipulated sensors
Intercepted payout signals
Coordinated distraction and voucher theft
Modern machines are usually secured through locked cabinets, internal logs, surveillance, access controls, and restricted maintenance systems.
Cheating may require:
Intelligence with technical tools
Dexterity for physical tampering
Charisma (Deception) for impersonating staff
Stolen credentials
Insider cooperation
A successful intrusion may alter one machine or one account. It should not automatically compromise the entire casino network.
Casino staff may detect manipulation through:
Unusual payout patterns
Machine error reports
Access logs
Camera footage
Open cabinet sensors
Voucher inconsistencies
Employee records
Statistical review
Missing or altered hardware
Casinos may allow a suspicious player to continue while security gathers evidence.
Possible consequences include confiscated winnings, detention, a permanent ban, police involvement, private questioning, blackmail, or faction retaliation.
A machine may malfunction because of:
Software errors
Damaged components
Network failure
Improper maintenance
Deliberate modification
Power interruption
A displayed jackpot may be disputed if the machine records show a malfunction. The casino may inspect the machine before paying.
An illegally operated machine may use concealed settings that provide worse odds than advertised.
Detecting a rigged machine normally requires observation, records, technical access, or repeated results rather than a single unlucky spin.
For a short session, the player chooses a stake and risk level:
Cautious: Small repeated wagers
Standard: Moderate wagers
Aggressive: Large wagers and jackpot-focused machines
Roll 1d20:
1–6: Lose most of the session stake
7–11: Moderate loss
12–14: Break roughly even
15–18: Moderate profit
19: Major profit
20: Jackpot or major bonus opportunity
Aggressive play increases the size of both losses and winnings. Cautious play reduces both.
Franz should state the wager, available credits, jackpot conditions, and result of each important spin.
Slot machines work well as background gambling, money-laundering tools, sources of surveillance footage, targets for hacking, disputed jackpots, planted evidence, and meeting places inside busy casinos.
The player controls how much to wager and when to stop.
