step 1 / 5
A sun emitter fires a beam in one fixed direction. The arrow spoke shows which way.
step 2 / 5
Tap any empty cell to drop a mirror. Each tap flips it: / → \ → remove. Mirrors turn the beam 90°. Fire as many times as you want — only your best run counts.
step 3 / 5
Thread the beam through every cyan crystal and have it end at the gold focus. The focus ignites.
step 4 / 5
Purple voids absorb the beam — route around them. Reaching the focus is always a win. You get ★ for that, ★★ for lighting every crystal too, and ★★★ for every crystal within par mirrors — par is the route a careful observer needs, and it is rarely the obvious one. On Medium and Hard the ★★★ must also land within a beam budget (shown by Par) — plan the line before you fire.
step 5 / 5
Easy feeds your streak. Medium is a bigger 8×8 plate with more crystals to light. Hard adds portals — paired brass gates; the beam that enters one leaves its twin heading the same way. Medium and Hard don't feed the streak — they earn bonus crystals.
