Game concepts

  • 2048 — Based on the original game by Gabriele Cirulli (2014). The 2048 game concept is open source under the MIT License.
  • Sudoku — Sudoku puzzles are in the public domain. The modern number puzzle was popularized by Maki Kaji (Nikoli, 1984) and the name "Sudoku" is not trademarked in most jurisdictions.
  • Stroop Test — Based on the Stroop effect, first published by John Ridley Stroop (1935). The psychological concept is in the public domain.
  • Go/No-Go — Based on the Go/No-Go paradigm, a standard cognitive neuroscience task in the public domain.
  • Multiple Object Tracking (MOT) — Based on the MOT paradigm by Zenon Pylyshyn and Ron Storm (1988). The experimental paradigm is in the public domain.
  • Flappy Bird / Pipe Dodge — Inspired by the "flappy" mechanic genre. The tap-to-fly-through-gaps gameplay is a common game mechanic not subject to copyright.
