A puzzle problem from James Tanton that I enjoyed: Can the faces of 27 unit cubes be painted red/green/blue is such a way that they can be assembled (in different orientations) to make an all-red cube, an all green-cube, and an all-blue cube? ("All-red cube" means all the exposed faces are red, and all the blue and green faces are hidden.)

“A simple dice-throwing game that seems hard to play” https://blog.plover.com/math/dice-game.html : start with a pool of _n_ points; choose a 4-, 6-, or 8-dided die, throw it, subtract from your points pool. If the pool reaches 0 exactly, you win; less than 0 you lose. What's the optimal strategy and its chance of winning?
