British Canister deals the whole pack face up into eight columns of six and seven cards and gives you no stock at all. Everything is in view from the first move. The tableau builds down in alternating colours, one card at a time, and the rule that gives the game its teeth is the space: an empty column takes only a king. With every card visible and no luck left to come, British Canister is a pure planning game, and one of the family's harder ones.
Count the moves before you make the first. Nothing is hidden, so a chain of single-card moves can be planned to the end. Look for the aces and the twos first: each one is buried under a known number of cards, and the cheapest one to reach is where the game starts.
A space is only worth what a king can do with it. Emptying a column is expensive with single-card moves, and only a king may enter it. Before you clear a column, find the king that will take it and make sure the cards on that king have somewhere to go.
Build hosts, not towers. Because only one card moves at a time, a long alternating run is a liability: every card in it has to be lifted individually to reach what is beneath. Keep runs short and keep the low cards you will need soon near the top.
Two hosts, both visible. Every card has exactly two cards it may land on, and you can see both. Before you cover one, check that the other is free or will be.
The Beleaguered Castle family is the open, stockless line of patience: every card is dealt to the table and the game is decided by planning. Its members vary the build, what an empty column accepts, and the deal. British Canister comes from the Canister line — American Canister opens its spaces to any card and lets packed runs move; Canister builds by rank — and is the strictest of the three: alternating colours, one card, kings only. It plays like Castles in Spain with the space rule turned against you.

Two ways. Eight columns of six and seven replace thirteen columns of four, and an empty column takes only a king where Castles in Spain takes any card. The alternating-colour build and the one-card move are the same.
No. All 52 cards are dealt face up into the eight columns, and there is no stock. What you see is the whole game.
No. Only the top card of a column moves, one card per move, however neatly the cards below it run.
Only a king. That makes a space expensive to earn and worth planning for.
Neither. Everything is on the table from the start and the game is decided by the order of your moves.
American Canister deals the same board but lets any card fill a space and lets packed runs move. British Canister allows only kings into a space and moves one card at a time, which makes it the harder game.
