step 1 / 4
The beam
A sun emitter fires a beam in one fixed direction. The arrow spoke shows which way.
step 2 / 4
Mirrors bend
Tap any empty cell to drop a mirror. Each tap flips it: / → \ → remove. Mirrors turn the beam 90°.
step 3 / 4
Crystals + focus
Thread the beam through every cyan crystal and have it end at the gold focus. The focus ignites.
step 4 / 4
Voids & stars
Purple voids absorb the beam. Scoring: par mirrors = ★★★, par+1 = ★★, more = ★. Daily feeds your streak; Challenge is bigger & harder.
