Sequence (Notebeck)

Sequence is a small daily puzzle from Notebeck, the two-brother studio of Carter Beck, who designed it, and Aidan Beck, who programmed it. A new board appears every day on notebeck.com, dated under the grid, and every player gets the same one.

The board is a 4 by 6 grid of numbered tiles from 1 to 9, with a green START tile, a checkered END tile and a couple of black squares that block the way. Above the grid runs the sequence itself, a repeating row of plus, times and divide. Each tile you step on is combined with your running score using the next operation in that row, so the same 8 is worth a lot on a multiply and very little on a divide.

The puzzle is choosing the route: which tiles to take and in what order so that big numbers land on multiplies and small ones on divides, and how long a path to take before you turn toward END. When you reach END the game shows your moves and your score, tells you your place among everyone who solved that day and how many tied, and gives you a result to share.

There are no ads, no account and nothing to install, and the page works the same on a phone and a desktop. It suits players who like short optimisation puzzles that mix route planning with mental arithmetic.
