Sevens, from developer Nigel Hanbury, is a spin on the wildly popular Sudoku number puzzler, of which there are several variations in the App Store.
Just in case you've never played Sudoku before: The playing field consists of a 3 x 3 grid of squares. Each of the nine squares consists of yet another 3 x 3 grid.Your job is to fill in missing numbers from 1 to 9 in rows and columns without using the same number more than once in all the rows and columns. Depending on the difficulty of the level you're attempting to play, some numbers already will be filled in to help you get started. It's not like arithmetic; it's more a process of elimination or fill-in-the-blanks.
Most people find it challenging, although some weirdos like my daughter and wife can knock these games out like a pro bowler knocks over pins in championship play. Me, I've never managed to complete an entire puzzle before giving up in frustration.
So, when I set out to review Sevens, "I'm thinking, hey, this has to be easier than Sudoku. It's only one grid, 7 x 7. How hard can it be to compared to regular Sudoku?"
But here's the catch: Sevens requires that you fill in the numbers in each row and square, using only the number 1 through 7. At the same time, you must insert the correct numbers into a color group that also must have only a unique number from 1 to 7. If you look at the screen capture on the left, you'll see exactly what I mean. It's almost like doing two games, one on top of the other.
Sevens also pits you against the clock and when I discovered that extra challenge, I knew I was pretty much sunk. This is a tough game for guys like me whose brains are stuffed with bits of junk that tend to get in the way of logic and rational thought processing.
Sevens has 3 levels and 200 puzzles in each, so anyone playing this app will find it will keep him or her busy from now until infinity, at least.
I've been working on Sevens off and on for the past week and I haven't made much progress. I tried to interest my wife into taking on the game but she's been too busy. I hope I get a chance to see how well normal people do with Sevens.
One thing I will say: Sevens looks a heck of a lot better than any Sudoku games I've tried on paper and online. Its graphics are polished; game play is smooth; and I didn't encounter any glitches or other weirdness
I don't even know why I'm mentioning this, but in an update, I'd like to see the option of being able to play head-to-head over a network. I don't know if my ego would be able to handle Sevens at that level, but I'm willing to give it a shot.
