Wide spreading wings over a slim body — the biggest open board in the library.
The butterfly is all wings: 186 tiles, almost all single-layer, with long horizontal rows that expose lots of free edges. That makes it a friendly board to learn pair-order strategy on — but a big one, so watch the slim body column: it connects the wings, and tiles buried behind body pairs can lock a whole wing. Clear wingtips first, keep body pairs unblocked, and the board folds itself open.
