Battleship, but every row and column is labeled in binary, the way a
computer counts. To call a shot you read a binary number, and your partner
reads one to answer. One game and you’ll have done dozens of conversions.
How to read a label
Binary works like decimal, except each place is worth double the place
to its right instead of ten times. In a 3-digit binary label, the
places are worth 4, 2, and 1:
Place value
4
2
1
Digit
1
0
1
Add up the place value under every 1 digit: 4 + 1 = 5. So the
label 101 means row (or column) 5. A label of 000 means 0, and the
biggest label, 111, means 4 + 2 + 1 = 7. Three digits, each either 0
or 1, give exactly eight different labels, so this grid has eight rows
and eight columns, numbered 0 through 7.
Each of you already has a fleet drawn on your own “My ships” grid
below, so there’s no setup: just start calling shots.
