What’s happening?

When you first read the rules of Sprouts, you might think it never ends – you’re always adding new spots to connect. But spots can be filled up, which gives us a hint why the game always ends.

Each spot can only have three lines coming out of it. You can imagine that each spot has three lives. On your turn, you draw a line that goes to two existing spots, using up one life for each. You also add a spot, but it already has two lines connecting it, so it only has one life left. You use up two lives and only add one. Eventually these lives will run out and you won’t be able to add more lines.

You can make the game end faster by separating the spots that are still alive. If a spot is encircled by lines, it can’t connect to a spot outside the circle – so the game can end while there are still several lives left. If you play with three spots at the start, the first player has to do this to win.
