Between two metro stops, or while the coffee goes cold, these are the games people keep returning to. A few spare minutes and an uncluttered mind are all most of them need. In block puzzles, spot the gap before you set down a piece. Card games call for some counting and a little patience. Everything else runs on reflex, which works perfectly well.
Pick Block Blast when fitting pieces into a grid appeals to you, or Solitaire for a deck and a calm table. Sudoku suits anyone who likes to ponder before tapping, while Moto X3M offers the reverse: one short track, a couple of flips, and a free restart. Faster and noisier, football and car games close out the list — handy for a quick round with a friend beside you.
