You could also try 'stalemate sevens', where you're not forced to go even if you can. Some groups force players to pay a forfeit or stake every time they knock. Basically, if you start with a handful of kings or aces, you're stuffed. No need for digressions about extra rules, stratagems and so on - there aren't any. The winner is the first to empty their hand. So a few turns into the game, the table should take the form of three or four suited columns of cards, each proceeding downwards towards the ace and upwards towards the king, as illustrated below. The only valid plays are to lay a seven, or a card of the same suit immediately above or below any other tabled card. If they have a seven, they play it, otherwise they knock, and the turn passes to the left. You may play only one card per turn and if you can't play, you pass or 'knock'. When your turn comes, you must play if you can.
Deal out the whole pack, one at a time, to all the players.
