ARC Game

Observations

  • I immediately observe "periodicity" in both inputs and output, and suspect that this is a pattern repeat task

  • I try a few combinations and I discover that indeed, this is a "pattern repeat" task -- from 2 repetitions to 3 repetitions

  • I observe that the foreground colour is consistent across the inputs and consistent across the outputs

  • I observe that different than in other riddles, the pattern always fills the whole board, and the board hugs the pattern, rather than the pattern extending inside the board

Concepts Used

  • Colour stats, take the most common foreground colour

  • Discover the element of the pattern if the pattern is already repeated

  • Extend the board size

Solution Approach

?

possible distribution shifts

  • the direction of the pattern

  • the count of the elements

  • the pattern element shape and size

  • the colors in the pattern can be arbitrary, not just mono
