Pastimes is a calm 2D logic puzzle based on Pieter Bruegel the Elder's painting Children's Games (1560). Players fill a large numbered grid where each clue indicates how many cells must be filled in the surrounding 3×3 area. Solving the puzzle gradually reveals the full painting, divided into scenes that unlock short notes about the historical games depicted. The game can be played solo or in local split-screen co-op on the same shared puzzle, with support for Steam Remote Play Together.
