Original team exercise

Reference-frame agreement

An unambiguous direction or color can still be applied to the wrong physical control. Write a shared reference frame and verify it with a harmless description before play.

Build your team card

Name the panel or physical region.

Which fixed edge defines up for this panel?

For example, describe positions from the agreed left edge.

How will the receiver confirm the same position without acting?

Your card

BOMBANANA — Reference-frame agreement
Team-authored plan; not a verified solver answer.
Panel identifier: [not agreed]
Reference edge: [not agreed]
Position naming order: [not agreed]
Read-back check: [not agreed]

Run this exercise

  1. Choose a visible fixed edge rather than a moving hand as the reference.
  2. Describe two different positions using your proposed naming system.
  3. Ask the receiver to point out or repeat each position using their available information.
  4. Resolve disagreements before attaching a real solver instruction.

Example to adapt

Practice only: agree a top edge, name a position from that edge, then have the receiver describe it back. Never infer a game panel layout from this example.

Completion check

If the panel orientation changes, re-establish the frame. The worksheet does not convert coordinates or verify game geometry.

Evidence and limits

This worksheet is an original BOMBANANA Solver coordination suggestion, published September 6, 2026. It is not an official manual, tested game strategy, or module solution. The official game description establishes the three asymmetric roles and player-designed communication; this site's exercises build on that context.
