How to Play

Enter your
digit sum S
and the
prime factors
(comma-separated), then press
Start Game
. S must be 7-smooth (only prime factors 2, 3, 5, 7).
Your
BINGO card
shows the prime factors as shaded cells — it stays pinned at the top while you play.
Go through the partitions of S below. Click
PASS
if the digits contain all entries on the BINGO card,
FAIL
if they don't.
Use
TOSS
for partitions with digits greater than 9 — the
Mass Toss
button tosses them all at once.
Prune
branches by clicking the first or second number of a partition — a whole block of FAILs will light up red.

to grade every row. The psi-number digit combinations appear in the Winner's Circle at the bottom.
