Also looking for more recs for games for the two of them to play together that are also not maddening for an adult. So far we love Uno, Spot It, Blink, and to some extent Rummikub cards (a bit hard for the 3yo). For reference, the 3yo can play a vagely serviceable game of chess and sustain attention for it, but he's only at an early reader level so games with reading don't really work. He can read numbers, use dice, and count just fine.
