Waxlight Vigil

Burn the whole candle network with one spark and make all three starred altar flames overlap at least once. Place one extra candle to bridge the cold gap. Two Wax dips add two beats of fuel to a chosen unlit candle, up to three. In Spark mode, tap the candle that starts the reaction. Each Burn step lights cold side-touching candles from the current flames, then uses one fuel from those older flames; newly lit candles keep their full fuel for that beat. Ash never relights. The two close altars need to remain alight while the longer branch reaches the distant altar. Planning ends after ignition; if the fire dies without burning everything and synchronizing the altars, restart and change the bridge or wax timing. Keyboard: Tab and Enter/Space operate buttons; R restarts.
