Use buttons and sensors so one program passes every test.
Free. No login. Needs a computer or tablet.
A room can run the program in two tests, and one program has to pass both. Students use buttons A and B, a light sensor and a temperature sensor to make it work.
On paper, students trace four rooms by hand. Here each room runs every test, so a program that only works for one reading fails where students can see it.
