In the lab of the eccentric Dr. Barabara, numbers are never what they seem. Each card can be broken down into parts, a 6 might become two 3s, three 2s, or even 1+2+3. In this chaotic experiment of numerical dissection, players scramble to shed their hands using clever recombinations and surprise prime number plays to dominate the discard pile and rise to genius status.

Dr. Barabara’s Bunkai Daifugō is a climbing game where every card represents a number that can be « decomposed » into smaller numeric sets. For example, a 6 card may be played as three 2s, two 3s, or a 1-2-3 sequence, giving players tremendous flexibility in play construction. Special « prime cut » rules allow players to reset the field with cleverly timed prime-number plays, opening windows for sudden victories.
