The four preference axes

The game groups situational choices into four axes. Neither side is a better personality, and your choices can change with the situation.

E / I · Extraversion / Introversion

Recharging through interaction or through time to reflect alone

S / N · Sensing / Intuition

Starting with concrete facts and experience or with possibilities and connections

T / F · Thinking / Feeling

Starting decisions with logic and criteria or with their impact on people

J / P · Judging / Perceiving

Preferring plans and closure or keeping options open and adapting

How to play Solo and Duo

In Solo, one person answers on a five-point scale. The game selects three prompts per axis, 12 in total. Allow roughly three minutes, depending on reading speed. You can also choose neutral.

In Duo, enter both people’s MBTI types, then take turns choosing A or B on the same 12 prompts. Each prompt has two answers, giving 24 responses when completed. Discussion may take longer than Solo. Fewer active questions can mean a shorter session.

Questions load when you start. If loading fails, try again later. This guide remains readable without a question request or an AI response.

Solo scores and the four letters

An outer choice adds 2 points to that trait; an inner choice adds 1. Neutral adds no points and is excluded from the analyzed response count. The higher-scoring side of each axis supplies one of the four letters.

The axis percentage is the leading side’s points divided by both sides’ total, rounded to a whole number. It is not a personality probability or diagnostic accuracy. When the points tie, E, S, T and J are shown as the respective letters. An axis with no points uses the default type, so do not read a result with insufficient answers as a measured preference.

If every answer is neutral, the game currently uses four built-in example answers to produce a fallback result. Its type and numbers do not measure your personal preferences.

An axis is classified as balanced when the point difference is at most 20% of the total. That classification is separate from the strength wording used in descriptions. A small difference that changes a letter does not mean a large personality change.

Duo comparisons and chemistry scores

Duo keeps the two entered MBTI types and pools both people’s choices by axis. The basic calculation marks an axis as synergy when both entered traits match its leading trait or the answers are sufficiently mixed. This differs from whether two people chose the same answer on an individual prompt.

Basic chemistry adds 9 points per synergy axis and 5 for each other axis, divides the sum by 4, then adds 58 and rounds. With four axes, the current rule gives 63–67. It is a game rule, not a relationship success probability or a validated compatibility score.

The basic detail metrics use these rules: balance averages how evenly the two traits appear on each axis; stability is 40 + 15 per matching letter in the entered types; growth is 60 + 4 per N, F or P response, capped at 95. These do not measure psychological stability or real growth ability.

When AI explanations are available, the page shows matching and different answers, conversation cards and axis suggestions in place of the basic score view. Per-prompt comparisons include only prompts with both responses. Matching choices can have different reasons, so ask each other why.

Worked examples

Solo example: a strong E choice worth 2 points, a mild E choice worth 1 and a mild I choice worth 1 give E = 3 and I = 1. The leading share is 3 ÷ 4 = 75%, showing an E lean in these choices. Neutral answers do not enter that total.

Duo example: if ENFP and ISTJ each choose opposite sides once on every axis, the points tie on each axis and all four count as synergy. Basic chemistry is 67, balance is 100, stability is 40 and growth is 72. Different types or answers do not imply a bad relationship.

Try this conversation: one person wants to book a weekend ahead and the other wants to decide on the day. Agree on one essential booking and leave the rest open. Check whether this small agreement helps in real life rather than treating the score as the outcome.

AI explanations, storage and sharing

Fixed calculation rules produce the basic axes and scores. After completion, answers and types go through the server’s Gemini analysis to add explanations. AI text can be wrong. If generation fails, the basic calculated result remains available.

Detailed answers and results are saved in temporary storage tied to this browser tab. Refreshing a matching result in the same tab attempts to restore it. Closing the tab, clearing data or blocking storage can prevent detailed restoration. Solo requests AI again on restoration; Duo requests it when no saved AI explanation is available.

Shared URLs contain type information, not the original answers or full AI text. A shared page in a fresh browser without saved data shows a basic reference analysis and fallback notice, without requesting AI. Do not read it as a restoration of the original session’s scores or personal explanation.

Using the result and understanding its limits

Choose what fits your recent behavior, then compare the result with a specific situation from the past week. If an explanation feels unfamiliar, check how you understood the question instead of forcing yourself to fit a label.

This game is not a validated psychological test, medical diagnosis, ability assessment or relationship prediction. It is a reflection aid built from short prompts and choice rules. Do not base important career, health or relationship decisions on the score alone.
