Eight if/else games
Conditions are how Dart makes decisions. Each game teaches a different angle — reading, tracing, building, and finally writing conditions yourself.
Complete all eight mini-games to master branching logic.

What is an if / else condition?
A condition is a decision point in your code. Dart checks whether something is true or false and then runs different code depending on the answer.
if (score >= 90) {
print("You passed!");
} else if (score >= 60) {
print("Almost there.");
} else {
print("Keep practising.");
}
- if — the first check. Runs only when its condition is true.
- else if — a second (or third, fourth…) check. Only reached when the previous if was false.
- else — the fallback. Runs when none of the above conditions matched.

Stage 1
Traffic light
Pick the right if/else branch for each light colour.
The traffic light is showing a colour. Read the Dart code and choose what happens next. Each round teaches you a different branch.
if (light == "green") { go(); }
