How It Works

  1. 1

    Pick each character's zodiac sign (the game's 12 signs) and personality type (one of the 16 in-game personalities, each mapped to an MBTI 4-letter code by the community).

  2. 2

    The calculator reads the zodiac synergy matrix (0-100 per sign pair) and applies the personality complement rules: Outgoing pairs with Independent, Confident pairs with Easygoing for romance; same-group pairs boost friendship.

  3. 3

    Both scores are normalized to 0-100. Romance = zodiac weight (50%) + personality complement (50%) with a +/- modifier. Friendship uses the same base but rewards same-group pairings instead.

Frequently Asked Questions

Is this compatibility calculator official Nintendo data?

No. Tomodachi Life itself has no in-game 'compatibility score' UI. This tool is a fan-made model that combines a community-interpreted zodiac synergy matrix with MBTI-style personality complement theory. The 16 personality-to-MBTI mapping is community consensus, not an official Nintendo classification.

Which personality type is most compatible with mine for romance?

By the complement rule used here: Outgoing pairs best with Independent, and Confident pairs best with Easygoing. Same-group pairings (two Outgoing, two Easygoing) score higher for friendship than romance, mirroring how the game's residents naturally bond.

Can I use this for Tomodachi Life: Living the Dream on Switch?

Yes. The Living the Dream remake on Nintendo Switch keeps the same 16-personality system and the 4-dimension (Movement, Speech, Energy, Thinking) slider model, so the compatibility framework applies directly. Create both Mii in Mii Maker, then use this tool to plan their pairing.

Does my data get uploaded to a server?

No. All computation happens in your browser using native JavaScript. No zodiac, personality, or Mii data is ever sent to a server. The page is a static export and works fully offline after first load.
