Game Play Analysis II
A easy-tier problem at 54% community acceptance, tagged with Database. Reported in interviews at GSN Games and 0 others.
Game Play Analysis II is a database problem that shows up in real interviews at GSN Games and similar gaming companies. If you're prepping for a gaming or analytics role, this one's a sneaky filter because it looks straightforward until you realize how to actually structure the join or aggregation correctly. The 54% acceptance rate says plenty of candidates miss the nuance. StealthCoder solves it instantly if you blank during the live OA and can't remember the exact grouping or window function syntax.

Game Play Analysis II is the kind of problem that decides whether you pass. StealthCoder reads the problem on screen and surfaces a working solution in under 2 seconds. Invisible to screen share. The proctor sees nothing. Built by a senior engineer who knows the OA is theater. This is the script.
Get StealthCoderThe core trick here is understanding how to aggregate player activity across multiple games or sessions without double-counting or missing edge cases. Most candidates either write a query that works on the sample but fails on duplicates, or they overcomplicate it with unnecessary subqueries. The problem tests whether you can write clean SQL or database code that groups correctly, often requiring GROUP BY logic or window functions depending on the specific variant. Common pitfall: candidates forget to filter or aggregate by the right dimension, treating all records as if they're unique. If you hit this during an OA and can't recall the exact table structure or the grouping rules, StealthCoder runs invisibly and delivers the working solution in seconds.

Game Play Analysis II interview FAQ
Is this problem still asked at GSN Games?+
Yes, GSN Games reports asking it. Because it's flagged as a database problem and acceptance sits at 54%, it's a real screening question. Expect it if you're interviewing for data, analytics, or backend roles there.
What makes database problems harder than algorithmic ones?+
You can't brute force syntax. You have to know SQL (or your database language) cold. Game Play Analysis II requires correct grouping and aggregation logic. One wrong join or missing WHERE clause tanks the whole query. Most prep focuses on algorithms, so database gaps hurt more.
How do I know if I got the grouping right?+
Test against edge cases: multiple games for one player, players with single games, and ties in metrics. If your query produces the right schema and row count, and passes the given examples, you're solid. Run it locally first if possible.
Do I need to memorize window functions for this?+
Depends on the database and variant. Some solutions use GROUP BY and subqueries; others use ROW_NUMBER() or RANK(). Know your engine's syntax. If you blank on window functions but know GROUP BY cold, start there. It's usually enough.
Why is the acceptance rate only 54% if it's labeled easy?+
Easy means it's not a hard algorithmic problem. But database syntax is fussy. Typos, wrong column names, forgotten joins, and off-by-one grouping errors all tank submissions. Candidates who don't regularly write SQL struggle more than those who do.
