Goal

Every scale shown is level, so its two pans weigh the same — "1 star = 2 hearts". Use them to answer the gold scale: how many of the symbol on the right balance its left pan? Answer as many as you can in 60 seconds.

Levels

• 3 right at a level moves you up; 2 misses in a row move you down.
• From one scale and two symbols to three scales and four symbols, with bigger pans.
• From level 7 the same symbol can sit on both pans — take it off both sides. At level 8 the answer can be in any symbol.

Scoring

A right answer earns 3 + 2 × the level, plus 1 for every 2 in a row (up to +3). A miss costs 2 + the level.

Step-by-Step Logic

Chaining facts — if this equals that, and that equals two of those — is the core of reasoning and of algebra, done here with pictures instead of letters.
