You might like to have a go at the game Last Bead before this one.
This is a game for two players.
Take turns to remove as many driplets as you like from a single driplet trail. Click once to choose, and once again in the same place to confirm.
The winner is the person to take the very last drip or drips.
Below you can play against Al, our computer, but you can also play offline against a friend using coins or counters arranged in heaps instead of drips arranged on drip trails.
Press 'New Game' to start, you then have 20 seconds to make the first move before Al, the computer, loses patience and starts anyway.
Can you find a winning strategy?
Hint: Count the drip trails with single drips and those with two drips: are those numbers even or odd? How might this help you find a strategy? You can also watch Rachel and Marianne play the game to see how they got on.
