SQL games guide
The best SQL games to actually learn SQL, ranked.
Most SQL games are fun once. We played all nine and scored each one on five things you can check, from how much SQL you write per minute to how far the game takes you.
We played every game end to end and recorded which SQL each one teaches. Every score is in the table below, and the order comes from the scores and four tie-break rules. Then each game has a full review. Full disclosure: we make two of these games (SQL Block Game and Station Zero). We say where the others beat us, and when we tie with another game, the other game ranks higher.

Not games, but useful: SQLBolt and SQLZoo for short interactive lessons, Postgres Exercises for problems up to recursive CTEs and window functions, and GalaXQL, which teaches table building and triggers in a 3D galaxy. SQL Protocol, a story game with 15 chapters, was offline when we checked on October 19, 2026 (its server returned "Application not found"). We will test it again when it is back.
How we scored them
Five axes, 0 to 2 points each, so the maximum score is 10. All five axes have the same weight. The first two reward practice: you learn SQL by writing it, and you keep it when you write it again on another day.
- 01
SQL per minute. How much of your time goes into writing SQL. 2: a new task every minute or less, with no story, map or menu between tasks. 1: SQL is the main activity, but story, clues or one long task come between your queries. 0: most of the time goes to other things.
- 02
Come back tomorrow. Whether you get new practice when you play again. 2: every run is new and the game does not end. 1: a large free set, 50 levels or more, to work through. 0: one story or a short set that you finish once.
- 03
Real database. Whether a real SQL engine runs your query. 2: yes. 0: a homemade engine, which can accept SQL that a real database rejects, and the reverse.
- 04
Tells you why. What happens when your query is wrong. 2: it shows what is wrong, for example the missing columns or rows. 1: it gives hints. 0: it only says correct or incorrect.
- 05
How far it goes. The most advanced SQL that the game asks for. 2: window functions or CTEs. 1: multi-table joins or subqueries. 0: one join or GROUP BY.
When two games have the same score
- More SQL per minute ranks higher.
- Then a higher Come back tomorrow score ranks higher.
- If two games still tie and we made one of them, the game we did not make ranks higher.
- Then a higher How far it goes score ranks higher.
Every game, reviewed
1. SQL Block Game The most SQL per minute, and a new run every time
Best for: daily practice of the SQL you already know, until you write it fast and without errors.
Query cards fall into a pixel-art well. Write the SQL that answers a card before it lands, and the card clears. Cards that land stay on the stack, and the cards fall faster at each level. Every query runs on real Postgres in your browser and is checked by the rows it returns, so any correct query counts.
It covers WHERE, ORDER BY with LIMIT, COUNT, SUM and AVG, and GROUP BY, in a Fill the blank mode and a Full query mode. In the runs that players finished in October 2026, the median run lasted about three minutes and cleared about ten cards. No other game here asks you for SQL that often.
Each run shuffles the cards into a new order, and a daily leaderboard gives you a reason to play again tomorrow. You can play as a guest. Each tier links to the free lesson for it.
Where others beat us. It stops at GROUP BY on one table: no joins, no subqueries, no window functions. It drills what you already learned and teaches no new concept. To learn new SQL, SQL Case Files, Lost at SQL and Station Zero all go much further.
Play SQL Block Game →2. SQL Case Files The most levels, behind a name-gate
Best for: a large volume of detective challenges with real depth.
About 100 levels on a real in-browser database, and it genuinely climbs, all the way to window functions and CTEs across its later seasons. It grades by matching your output and enforces column names, with light hints. It asks for a detective name before you can play.
Visit SQL Case Files3. Lost at SQL Charming, and clear about why you are wrong
Best for: one relaxed sitting with real feedback.
A sinking-submarine text adventure that quietly goes further than it looks, reaching window functions inside multi-step queries. Its grader is one of the two most helpful here: it tells you which columns and rows are off, and tracks your time and mistakes as a score. It is a single experience with nowhere to go after.
Visit Lost at SQL4. Station Zero The deepest story, and the best help when you are stuck
Best for: a story-driven game that goes from your first SELECT to recursive CTEs.
You wake on a dying space station. The only system online is CORA, the station computer, and you talk to it in SQL. Across three acts, Station Zero goes from your first SELECT through anti-joins, GROUP BY, HAVING and subqueries to window functions and recursive CTEs.
When your query is wrong, CORA tells you what is wrong and why, and the help gets more specific the longer you are stuck. When the story ends, it opens into a free 66-lesson SQL course.
Where others beat us. Story scenes and act breaks take time that is not SQL, so it scores lower than SQL Block Game on SQL per minute. It is one story, and when you finish it, it is done. SQL Case Files has more levels. Lost at SQL explains a wrong query as well as we do, and it ranks above us because a tie goes to the game we did not make. Station Zero is SELECT-only, where SQL Island teaches you to change data.
Play Station Zero →5. SQL Squid Game The funny one that sells you a course
Best for: a laugh, and a nudge toward structured interview prep.
Nine levels of Squid Game parody that get surprisingly deep, with chained CTEs and correlated subqueries, but skip window functions. It grades by matching output with a plain Incorrect, no explanation, and level one is already hard for a true beginner. The smartest funnel in the category, straight into DataLemur’s tutorials.
Play SQL Squid Game6. SQLNoir The most polished game on the list
Best for: a beautiful, story-first detective game when you already have a little SQL.
Takes you through filtering, multi-table joins, and subqueries across six cases, and it is the best-made game here. It stops at intermediate: no window functions, no CTEs, and it never explains a wrong query. You run queries to surface clues, then submit the culprit and it is right or it is not.
Visit SQLNoir7. SQL Island The original, and the only one that teaches data-editing
Best for: nostalgia, and learning to change data, not just read it.
Crash-land and use SQL to survive. Alone among these games it teaches INSERT, UPDATE, and DELETE, and you literally delete the villains to win, alongside filtering, grouping, and a join. It runs real SQL and advances the story when your result is right. It shows its age and tops out at group-by.
Visit SQL Island8. SQL Murder Mystery The classic first hour
Best for: your first taste of SQL, or a one-hour classroom activity.
The iconic on-ramp. You explore a database from scratch and query your way to a killer, which gives you the real feeling that querying is investigating. It only ever needs one join and a bit of filtering, gives no feedback, and once you solve it in about 45 minutes you are done.
Stuck? Read our full walkthrough, with hints for each step
Solve the mystery9. SQL Police Department Clean drills, but paid and not a real database
Best for: guided, click-to-build beginner practice.
Introduces filtering, sorting, and eventually one join at a steady pace with helpful nudges like asking whether you used DISTINCT. Two catches: after a few free cases you must pay, and it runs a homemade SQL engine rather than a real database, so it never goes past a single INNER JOIN.

Are SQL games actually a good way to learn?
Yes, with two conditions. A game gives you a reason to write real queries, and that is better than dry exercises. But most SQL games end after one story, and you forget what you do not practice again. The games that make you good tell you why you were wrong and give you a reason to come back the next day. That is why our scorecard rewards SQL per minute and new practice on each visit.
For that path, go to the SQL course behind the game. Its lessons come in order, and each lesson has graded practice.
