You’re playing with 16 cards: two copies of each number 1 to 8 (and 1 means “ace”).

The two players

• Chooser: tries to find a starting number that makes the jumps go past the end of the deck.
• Arranger: tries to set up the deck so that every starting number ends on the very last card, and that last card is a 1.

Setup

1. The Chooser gets a bunch of white cards (numbers 1–8, with duplicates) and puts them in any order as a row.
2. The Arranger gets some blue “extra” cards (there must be at least one 1) and is allowed to slide them in between the white cards.
   • Important: the Arranger cannot change the order of the white cards — only insert blue cards between them.
3. Now the deck is finished and has 16 cards total, left to right.

Playing the jumping game

1. The Chooser picks a starting number N between 1 and 8.
2. Put a marker (a “dot”) on the Nth card from the left and look at its number. Call that number M.
3. Move the marker M cards to the right and look at the new card’s number.
4. Keep doing that: jump by the number you just landed on.

Who wins?

• If a jump would make the marker go past the last card, the Chooser wins.
• If the marker lands exactly on the last card, and that last card is a 1, the Arranger wins.
