About Summit (PuzzleLab)

Summit is one of the free daily puzzles on PuzzleLab, a collection of small browser games with no sign-up.

The board is a pyramid of number tiles. In a finished pyramid, every number equals the sum of the two numbers directly below it. Each day's tiles start out of place, and you swap them until the whole pyramid adds up.

The game counts your moves, so the aim is not only to solve it but to do so efficiently. A hint button helps if you are stuck, and you can end the round with I'm done. A new pyramid comes every day.

It suits players who enjoy arithmetic logic and want a short daily number puzzle.

Tips

The top number is fixed from the start, so begin by finding the pair in the row below that adds up to it.
Work from the bottom row up, since each row fixes the one above.
Check small sums first: they leave fewer options.
