Make a Tiny Game — The Foundry

What is a game made of?

Not magic. Just three plain pieces, all written in code.

Rules What is allowed and how you win. You will set these in a second.

Input What the player does. Here, that is the number you guess.

Response What the game says back. Higher, lower, or you won.

A game is rules plus input plus response. The page will hide a secret number. Your job is to find it. After each guess it answers higher or lower, and counts your tries. All of that is just code following a rule you can read.

Set the rules

You are the maker now. Pick how hard it is, then give your game a name.

Highest number the secret can be

20

The secret will be somewhere from 1 to this number. Bigger means harder.

Name your game Up to 28 letters. This shows at the top while you play.

Those two choices are your rules. Real game makers tune numbers like these for hours to get the difficulty just right. Change them, play, and feel the game change.

Play your game

The page picked a secret number. Type a guess and press Guess. It will tell you higher or lower.

Secret Number Hunt

Secret is from 1 to 20

Make your first guess.

Tries: 0 Range left: 1 to 20

See the three pieces working? Your typed number is the input, "higher or lower" is the response, and "find the secret in as few tries as you can" is the rule. That is a whole game, and you just made it.
