In development
A night of party games.
One phone.
GameMaster is a collection of games for parties and get-togethers. Truth or Dare, Werewolf, King’s Cup, Charades, The Impostor and more. Put the phone in the middle of the table and pass it round. It deals, it keeps score, it settles arguments.
Free. Works offline. Android and iOS.
Truth
What’s the most ridiculous thing you’ve ever cried about?
Real cards from the app’s decks. Deal a few and the heat climbs.
How it plays
It runs the evening.
Nobody has to be the one who knows the rules. Every game carries its own, so you open it and start, and the twenty minutes of arguing about how it actually works never happen.
Pass and play
One phone for the whole room. Nobody else installs anything, and nobody sits out because their battery died.
It deals, you play
Prompts, turn order, scores and tie-breaks are its problem. You just answer the card in front of you.
Four intensity tiers
Dial each game up or down. The same deck plays with your parents at Christmas and your flatmates at 2am.
Works anywhere
Every game and prompt ships inside the app. No signal, no sign-up, no ads, and nothing to load when you open it.
The games
Every game in the deck.
Prompt games, hidden-role games, drinking games, things you have to act out. Some fill the five minutes before the pizza arrives; others can take the rest of the night.

The Gauntlet
No pauses. No mercy.
The instruments
And nine tools, for when you don’t need a whole game.
Someone has to go first, the room has to split into teams, a bet has to be settled. Each one opens in a tap and does exactly one thing.
Dice
Roll one, or a handful.
The Coin
Heads, or tails.
Pick a Card
The Master turns one.
The Verdict
Ask; the Master answers.
The Number
A number, at random.
Finger of Fate
The Master points.
Divide the Room
Two sides, or more.
Running Order
Who goes when.
The Hourglass
Time, when you need it.
House rules
Set the room’s limits once.
Every group has a different tolerance, and most party-game apps ignore that entirely. These are set before you start and hold for the whole night.
The forfeit
You write what refusing costs, in your own words: a shot, a slap, an item of clothing, twenty press-ups. Whatever you type is what the app holds anyone who won’t answer to.
The Veto
Everyone gets one free pass per evening, with no forfeit owed. Nobody has to explain why.
The House Blend
Instead of choosing a tier every time you open a game, set one dial for the whole night. Every deck is then mixed to match it: mostly gentle cards at the low end, mostly the brutal ones at the top.
Topics off the table
Rule out exes, family, work, body or gross and they disappear from every deck for the night.
The Master’s tricks
A thumb on the scale.
A trick weights the randomness in someone’s favour. Whoever owns the phone picks a guest, or a pair, and sets how big a share of the outcome they get: who the bottle lands on, who gets called out, who the dare goes to. Everyone else splits what’s left, so it still plays like chance.
Two of your friends have been circling each other since spring and neither will move first. Set them as a pair, give them 60%, and the evening keeps quietly putting them together: the bottle, the dare, the question about who they’d choose. To the table it just looks like a good night.
Spin the Bottle: the odds
- Marco - spinning 0%
- Sofia 33%
- Anna 33%
- Luca 33%
Marco is spinning, so he can’t land on himself. Everyone else splits whatever share you haven’t handed out.
Favour a guest
One name comes up more often: who the bottle picks, who gets called on, who the dare lands with.
Favour a pair
Two names find each other, both ways, whichever of them is spinning. It sleeps until one of the pair is up.
Loaded dice
The same weighting works on the tools: how often the coin comes up heads, which total the dice land on, which way the oracle answers. The card still travels through the shuffle and the dice still show different pips, so nothing looks staged.
Protection
And a way not to get caught.
A trick only works while nobody has read it, so the page sits behind four digits. There is also a second four. Type those instead and the app opens a different collection entirely: plausible, dull, innocent. You keep it stocked for the moment somebody grabs the phone and demands to see what you’ve been up to.
Your four digits
Asked for every time you open your tricks. Until they’re typed, there is nothing on the screen to find.
The decoy four
A second PIN opening a second collection, one you wrote to look boring. Hand the phone over, let them scroll, take it back.
Burn it all
One command wipes every trick, the decoy collection and both PINs. No password asked for, and no undo.
Screens
A look inside.
The parlour is candlelit by default. One switch in Settings raises the blinds and the whole thing turns to parchment, which is the version that survives a kitchen table in daylight.
Early access
Get it when it lands.
