Math: Skat[1] is an awesome card game with rules that fit on the back of a single card (basic version) and that trains addition and multiplication. AFAIK it is/was accepted as a teaching tool in Thuringia's schools. (usually for 3 players, a 2 player variation is described in the WP-article). Literature: A membership in the local library was enough for me. Problem Solving: Chess and related board games; any kind of puzzles - I loved metal puzzles where I had to separate/join pieces (e.g. those found here[2] - not endorsing the shop, just the first hit on DDG).
