Solstice Jar
Bottle an 8 during BOTH dawn and dusk. Tap a column to drop the next number. On DAWN pours, matching numbers merge downward; on DUSK pours, they merge with a same-row neighbor (left first). Each merge doubles the value and settles it down, allowing chains. An 8 is bottled and removed. Every pour alternates dawn/dusk. Hold trades the next token with storage without changing phase. Finish within 18 actions; overflow loses.
Tap tiles, or use Tab and Enter. Arrow keys move board focus.
Challenge notes & source
Victory ends the run. The visible action reserve is a turn-based substitute for arcade time pressure: every accepted action costs one; zero remaining ends in defeat. Reset restores the seed.
Alternating merge directions and two separate essence goals require planning across columns, not repeating one stack.
