Java Cricket — twelve balls of Java. Play what you know, leave what you don't.
A target, twelve balls, and sixty seconds a ball. Every delivery is one Java question with four strokes on it. Pick the right one and it pays by the clock — six if it went inside twelve seconds, down to a single at the death. Pick the wrong one, or none at all, and you are bowled for four. Leave it alone on purpose and it is a dot ball, costing only the ball itself.

Twelve topics are on the syllabus and a match prefers one it has not bowled yet, so twelve balls are twelve different ideas:
The difficulty climbs across the over rather than sitting flat:
| Balls | Band | What it asks of |
|---|---|---|
| 1–4 | easy | somebody who has written a first class |
| 5–8 | medium | somebody who has finished a tutorial |
| 9–12 | hard | somebody who has read another person's code and worked out why it broke |

The clock is the scoring. Every button is worth the same, so the difference between a single and a six is only how fast the Java was read. Inside the first fifth means the snippet was read and the answer known; the last fifth means it was worked out — which still counts, but only for one. There is no five, because cricket has no five.
The cricket is the mechanic; the Java is the point. Sixty seconds is long enough to read a snippet you understand and far too short to work out one you do not — so the clock sorts recognition from reconstruction without anyone having to ask you which it was. And because leaving a ball is a legal move that costs almost nothing, the game rewards knowing what you do not know, which most quizzes punish.
The first four balls assume you have written a class. If you have not yet, start there and treat the later balls as a map of what is coming.
No — there are no wickets. Every ball is faced however often you are bowled; being bowled costs four runs off the chase, not your innings.
Yes. Every game on SULULU is free and there is nothing to buy.
