About the Sumdinger leaderboard

A daily math game: six number cards, one target. Combine them with + − × ÷ and hit it exactly. Three sums a day, easy to hard, the same for everyone.

This board ranks every signed-in player’s best verified score in Sumdinger this week. Each player is listed once, with their best run: a better run replaces it, a worse one leaves it where it is.

How a run scores

  • Hit the target before the clock runs out for 100 marks; within 10 still earns marks. Hand in early to bank the time.

How to climb the board

  • Get close first, then fix the gap: 25 × 4 = 100 is a great start for 103, and a 3 does the rest.
  • Look at the target's last digit. A target ending in 5 or 0 often comes from multiplying by 5, 10, 25 or 50.
  • Make the numbers you wish you had: if you need a 12, maybe 3 × 4 or 7 + 5 is waiting in the cards.

Periods, ties and checks

All-time keeps each player’s best since the board opened. This week starts again every Monday at midnight New York time. Today starts again every day at midnight New York time, with one ranked attempt a day.

Equal scores share a place, and the run finished first is listed first.

A run records only your inputs. Our server plays them again with the same game code, and only a score the replay matches is verified. A person also checks the top 10 scores.

The board lists every player, guests under their generated name. Sign in with Google or Apple from a result to keep your scores and pick your own name. Bots, scripts and other automated or assisted play are not allowed (see our terms of use).

Automated or assisted play is not allowed on ranked boards. A person checks the top 10 scores and may hide any that break this rule.
