How it works
How two player games on one device work
Most online games assume the other player is somewhere else. You make an account, send a link and wait in a lobby. GamesDuo starts from the opposite case: the other player is already sitting next to you, and you have about a minute.
So the screen is split down the middle. The left half belongs to player 1 and the right half to player 2. Each of you gets exactly one thing to press.
Player 1 presses A. Player 2 presses L. The seven keys between them keep elbows apart.
Lay the phone flat between you. Each pad fills half the width, and both register a touch at the same time.
The five duo rules
A game goes on the site only if it passes all five.
-
1
One device
If a game needs a second screen, a link to share or a room code, it is a different kind of game. Here both players look at the same picture.
-
2
One control each
A for the left, L for the right, or one pad each on a phone. Nobody has to read instructions while the other person waits.
-
3
Fair on both sides
Both players get the same job and the same distance to cover. The only difference between the two sides is the colour.
-
4
Over inside a minute
Long rounds make the loser wait. Short rounds make the loser ask for another.
-
5
Rematch is one press
The score stays up and the same button starts the next round. No menu sits between two rounds.
Two fair questions
Why A and L?
They sit on the home row at opposite ends of a keyboard, about fifteen centimetres apart. Two hands fit without touching, and almost every keyboard can register both keys pressed together.
What does the bot do?
In the tapping games it presses five to six times a second with a little randomness. In Quick Draw it reacts between a quarter and half a second after the lamp lights. It never cheats and never learns.
