Documented steps

  1. Add scores: ZADD game:scores 1500 "alice" 3200 "bob".
  2. Get top-N descending: ZREVRANGE game:scores 0 9 WITHSCORES (zero-based inclusive indexes).
  3. Preferred modern form (Redis 6.2+): ZRANGE game:scores 0 9 REV WITHSCORES — ZRANGE with REV replaces ZREVRANGE.
  4. Paginate with ascending index windows: ZRANGE game:scores 0 9 REV, then 10 19 REV, etc.
  5. Negative indexes count from the end (-1 = highest-score member).
