Opacity is a puzzle game played on an eight-by-eight grid. Four balls are randomly hidden somewhere on this grid, and it's your job to find them. Your only tools are beams that you can fire into the grid. These beams interact with the balls hidden on the grid, and you must determine where these balls are hidden using only the information about the beams' interactions. The rules are actually pretty simple, but the results can be very complex!

The fewer beams you use, the better your score. But remember, it's not just about speed. The most important goal is to find all of the hidden balls every time you play a game. That can be the real a challenge!

Opacity is based on the board game Black Box published by Waddingtons and Parker Brothers.


• Simple rules which result in complex interactions

• Challenging game play with almost infinite possibilities; every game is different

• Saves games in progress so you can play any time

• Tracks the number of games you completed, the number of games you abandoned and the total time you spent playing

• Records information about the game with your best score and the game you completed in the shortest amount of time

Nice play, but strays slightly from the rules of the original game

Good simple logic game like the original "Black Box" board game. In the original, there was no "Miss" but it was just a "Reflection" that happened to go straight through (which could happen by bouncing off a combination of balls). I'd also love to see an update where you have the option to play with 5 balls (like the original game).

4/5 stars

Great app!!!

This is a blast from my childhood! Follows all of the rules of the original Black Box game and is perfect fun.

Not only did I buy a copy for myself, but I gifted one to my childhood competitor as well!

As soon as multi-player comes in I'm changing this to a 5 star review.

5/5 stars

Great classic game of hide and seek

This is the great classic mind bending puzzle game of hide and seek! I remember it based on the 1970's Parker Brothers board game "BlackBox"
what ever you do don't pass this gem up... I contacted the creator and he stated that with enough interest this app could go universal or have an iPad version (how awesome would that be to fill up my iPad screen) heck he even mentioned the possibility of a two player version... Come on board game/puzzle lovers give this game a try you will love it
