Base Trail

Convert a number, represented as a sequence of digits in one base, to another base by following a base trail.

A maintenance beacon board spells out numbers using a 3 x 4 grid of pipes, underscores, and spaces. Decode the digits, preserve any unreadable glyphs as ?, and join multiple rows with commas.

Track a signal beacon that awards points based on how close a shot lands to the center of a circular target.
