Puzzle games are the ones you play with the sound off. These three ask you to plan a move ahead rather than react fast, so they suit a queue, a train or a five-minute gap between jobs.
Every game here pays 4OVER4 coins, and coins buy extras inside the games: a hint, an extra life, more room. Nothing is generated by a model, and each game runs on your own device. Your wallet keeps the balance and the ledger.
