Scatterbox is a game of pure deduction. A handful of atoms are hidden in a grid. You fire a beam in from any edge, see where it comes out, and reason your way to what must be inside. No reflexes. No timers. No luck. Every board has exactly one answer, and it is always findable. There are only four things a beam can do: • Miss — straight in, straight out the far side. That lane is clear. • Hit — the beam never comes back. It ran into an atom head-on. • Deflection — passing an atom on the diagonal turns the beam ninety degrees. • Reflection — two atoms turn it back out the square it entered. Learn those four and you have learned the whole game. In the Ray Lab the atoms are visible: place them anywhere, fire beams, and watch every path bend, bounce, or vanish. BOARD OF THE DAY One puzzle a day, the same for everyone, built from the date. The difficulty rotates through the week — gentle on Monday, brutal by the weekend. Solve it to build a streak; miss a day and the streak resets. Your best streak is always on the home screen. FREE PLAY Set your own board — width, height, and atom count, up to 12×12 on iPhone and 16×16 on iPad — or switch on random mode and get a fresh shape every game. BUILT FOR THINKING • Every marker is numbered, so you are never guessing at colors • Dark mode and a color-blind friendly palette • An optional timer if you want the pressure, off by default • "Check" your guesses before you commit — for a small score cost • Reveal shows the full path every beam actually took Your score is the number of beams you fired plus a penalty for wrong guesses. Lower is better. There is no way to lose — only to solve it in fewer beams next time. Scatterbox plays entirely on your device. No account, no sign-in, nothing to sync. It works on a plane. Scatterbox is an independent game in the tradition of Black Box, the deduction puzzle designed by Eric Solomon in 1976. It is not affiliated with or endorsed by the original game or its publishers. Free to play, with ads. A one-time "Remove Ads" purchase turns them off for good.

Verdict
The clearest difference is ads: Slitherlink at none against Scatterbox's shown. Slitherlink also leads on iOS requirement (15.6 vs 26.5). Scatterbox's advantage is update cadence (every 2 days vs every 4 months). On price, in-app purchases and device support there is nothing between them.
