# Puzzle Moment vs SUM

Puzzle Moment and SUM are too close to call on the numbers: across 6 compared parameters — price, update cadence, ads and in-app purchases among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.

Both are free to download. Puzzle Moment sells 1 in-app purchase, starting at $2.99 per month and SUM sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Both ship on a similar rhythm, roughly every 3 days. Both last shipped on October 31, 2026.
