Game Day: SEQ

SEQ is a number sequencing puzzle game from 1Button with 280 levels. The premise is simple – each level is a series of squares laid out in a pattern. There are colored squares with numbers in them and grey squares with zeros in them. Your job is to trace a path from the colored squares to the grey squares. Each square along your path is given a number that is one less than the square before it. For example, if you start with a colored square with a '5' in it, you need to fill squares with 4 - 3 - 2 - 1 before landing on a grey zero square. If you have multiple number sequences to complete in a single puzzle, things get trickier. One sequence cannot cross the path of another unless the number in the earlier sequence where the two cross matches what you need to advance the current sequence. It's easiest to understand by watching 1Button's video:

SEQ starts with very simple puzzles that gradually get more complex. You cannot skip around, except among the puzzles you have completed or ahead if you have purchased keys to bypass puzzles you cannot solve. SEQ works well on iOS with its simple path tracing and the ability to play for short periods of time. SEQ is also the sort of game that I like to play while I'm listening to a podcast or music, and fortunately the sound effects, which can be disruptive when you are simultaneously listening to something else, can be turned off by swiping to the view to the left of the puzzles.

SEQ is $1.99 on the App Store with a $0.99 in-app purchase to buy five keys that allow you to bypass puzzles you cannot complete.
