A Single Stroke of Fireworks

Draw a line with your finger, and it becomes a fuse. Fire races along it, fireworks burst open, and the explosions spread to other parts of the line, creating a chain reaction across the night sky.

• A game spanning eight nights. Each night, a new fireworks mechanism is added (large ball, thousand wheels, lanterns, clouds, wet balls, rigged ropes, one-foot balls)
• The third and sixth nights are "grand finales." The way you draw the line changes (straight, mirror, darkness, instant)
• The shape of tonight's actual moon changes one rule. "Tonight's single stroke" changes at midnight every night, so everyone plays the same night together
• Your results show "brushstrokes" based on the line's shape. You can send links to compete on the same night or replay links of the best single strokes
• Currently at "Stage 1: Summer Festival by the River." If there's good response, we'll add the next stage with different scenery and mechanisms
