Concentration

I’ve always loved game shows. One of the cool things about a vacation day or snow day in the winter was that I got to see my favorites. The ones that stick out in my memory were the original Match Game late in the afternoon (I remember being disappointed with the changes made for Match Game ’73, though in hindsight, the changes were for the best), Jeopardy, with Art Fleming around noon time, and my all time favorite, Concentration, in the mid morning.

I think a big part of my attraction to Concentration was the marvelous game board. Thirty numbers, all on rotating trilons, with one face for the number, one face for the prize, and one face for the puzzle piece. Each puzzle was a rebus, spelling out a phrase with pictures.

(Yes, it’s cheesy by today’s standards.)

I worked my way through several versions of the home game, but they were always unsatisfactory in one way — no rotating numbers. The puzzle was on a scroll of paper, with clear slots for removable number and prize cards. The game play was the same, but the game board was different.

Introducing Concentration

I’ve long wanted to build my own Concentration game. About twenty years ago, I tried building my own trilon-based game board, but after building all the trilons, I couldn’t figure out how to make it work.

About four years ago, I started building a version in HTML and JavaScript. I got as far as a game board and score board that worked—prizes were distributed randomly, it detected matches correctly, it handled “take” and “forfeit” properly, but the gameplay was clunky, it didn’t handle end of game well, there was no option to replay,  and it looked crummy. I was intent on duplicating the original look of the original game, but it was unfinished.

Last weekend, needing something I could demonstrate, I picked the project up again and polished it up. Now, with the power of CSS transforms and transitions, I finally have my rotating trilons. I’m now using jQuery in the script, which has simplified transitions between stages of the game. With downloadable fonts, specifically Open Sans, I’ve made the game look a lot nicer. And the game play between turns is a lot smoother.

About the Game

My game uses the same game rules as the original game that ran on NBC from 1958 to 1973, not the later Classic Concentration version which some younger folks might be familiar with. There are thirty numbers, not twenty five, with some “Take One Gift” and “Forfeit One Gift” squares factored in. To guard against the “Forfeit” prizes, there are a couple of gag prizes as well.

There are currently five different puzzles; I plan to add more as I have time and can think of them—the structure of the script makes it very easy for me to add more puzzles. A while back I found “Rebus Font” which is a font made up from many of the symbols used on the original program.

Unlike the original, my puzzles are in color. The original producer, Norm Blumenthal, fought the switch to color, feeling that colored puzzles would give the solution away too fast. When NBC insisted on switching the show to color, he compromised by going to pink drawings on a maroon background.

At the moment, the game does not use responsive design; it works best on a desktop browser or iPad. This is the thing I intend to work on next. It also requires a recent browser that supports CSS transforms. I’ve discovered it doesn’t work properly in IE 11, but at the moment, I don’t have access to a machine to test it on. (UPDATE, February 2015: I’ve discovered the reason it doesn’t work in IE is because IE doesn’t currently support the “preserve-3D” transformation property. There are work-arounds, but I haven’t tried them yet.)

It currently doesn’t handle the “double wild” case, where one happens to pick a pair of matching Wild Cards; it should allow the selection of another set of prizes, but doesn’t.

I may add sound to the game; I have a recording of a trilon turning, but it needs cleanup.

One of the things that kind of surprises me (about myself) after the fact is that I’ve grown a little more willing to deviate from the look of the original. I guess that’s a sign of growth, or a willingness to make changes in service of a better result. In my original version, the scoreboard looked more like the original scoreboard, complete with serif based font, and the look of the Wild Cards. One of the things that had irritated me about the home games was that the Wild Card tiles didn’t look like the ones on television; in the original version, I created one that looked like the original. And yet… once I switched the prizes to Open Sans, the old style Wild Card stuck out like a sore thumb, so I changed them. Finally, I added a single player mode, so the user wouldn’t have to enter a pair of player names.

I hope you enjoy playing my version of Concentration.

  1. It’s absolutely gorgeous. Yeah, a small kink or two … but a ton of fun. Habit forming, even.

    Thanks!
