What NutHouse is
NutHouse is a game maker for your Mac. You draw sprites, build levels and write rules, and out comes a game you can play and share.

Three things make a game
Every NutHouse game is made of the same three parts.
| Levels | A game is a list of levels. Each level is a stage where things happen. You build them in the Level tab. |
|---|---|
| Sprites and objects | Sprites are the things that move: a hero, a ball, a slime. You can draw your own in the Sprite editor or pick one from the library. Other objects keep score, show words or make things happen. |
| Rules | A rule says โwhen this happens, do thatโ. NutHouse calls them events. They live in the Events tab. |
Here is a rule from Chocobreak, the bat-and-ball game you make in the tutorial.
What you do not need
NutHouse is free. The Mac app has no account and no sign-in and never needs the internet: your games are saved as .nuthouse files, like any other document. The browser version needs no download; a grown-up can add a free account so games live online and can be shared.
You do not need to type code. Rules are made by clicking: pick a thing, pick what to test, pick what to do. When you are ready for more, Expert mode lets you type formulas like Score + 10.
