Make constellations by connecting values that XOR to all zeroes or all ones.

Gameplay
Select an adjacent target using the crank or D-Pad (when docked), then press A to extend the constellation. All connected targets will be replaced by new targets if the bitwise XOR of their values ends up being all zeroes or all ones.
Scoring
- Base score = 2 ^ (number of targets connected - 3). For example, 3 targets = (2^(3-3)) = 1, 5 targets = (2^(5-3)) = 4.
- Maximum number of targets is 24.
- Bonus multiplier for completing a constellation with the same resulting bits as the previous one. For example, two constellations of size 3 may be worth 1+1=2 points if the XOR result is 0x0 and 0xF, or 1+(1*2)=3 if they both XOR to 0x0.
- The bonus multiplier is increased for consistently producing 0x0 or 0xF results, up to 4.
- 3x bonus if Bocchi is in the constellation.
- 3x bonus if Kita is in the constellation.
Thus, maximum score in a single turn is (2^(24-3)) * 4 * 3 * 3 = 75497472 = 0x4800000.
Strategy
For levels 1-4 (4bits), you can pretty much play randomly and the odds will be in your favor. That said, you will score more points if you play more deliberately.
For levels 5-6 (8bits), you can try building one digit at a time, finding target that would flip bits for one digit while preserving bits for the other digit. There is some amount of luck involved in finding targets that don't perturb the bits in undesirable ways, but the targets are generated to make this manageable.
Levels 7-8 (8bits) are very much impossible. You can set hint mode to "visible" to score points that way.
Trivia
Attract mode: wait 10 seconds at the title screen.
Debug backdoor: press Up, Up, Down, Down, Left, Right, Left, Right, then one more button to enable autoplay. Last button determines autoplay behavior.
