Numeri is the iPhone version of the popular puzzle game Slitherlink. The object of the game is to draw a single closed line between the dots that would leave all of the digits valid. A digit is valid when the cell containing it has as many line segments around it as the digit contained within.

Be careful, as each of the puzzles is not as easy as 1, 2, 3. Drawing that continuous loop is not a piece of pie, and, while the game is not for everyone, each of the puzzles has exactly one valid solution. While being fun and entertaining, if you were looking for a stress-reliever then perhaps this game may not be for you. The game screen is simplistic in nature, leaving all the room for a nevertheless effective gaming experience. A 5 by 6 grid containing numbers 0 through 3 within apparently random squares within it is your playground. By touching a cell, all the line segments around that cell are triggered, making the valid loop way more difficult to achieve.

From Charles Jamerlan comes what he considers to be the most addictive game for the iPhone. Surely a catchy name, but in this reviewer’s humble opinion not nearly a game worthy of it.

Throughout my Flash developing days I’ve come across several similar games for the web, and, true enough, with the emergence of the iPhone and the App Store porting such games for the OS mobile platform was inevitable. But perhaps some apps are better left to be enjoyed online, the old fashioned way with a mouse and starring at blank-point at the old-school computer monitor.

This iPhone game from the team over at Micromelon is designed to test your eye-to-hand coordination in a simple and fun way. Chase the big white dot on the wide black screen of your iPhone or iPod Touch and touch it before it disappears and switches locations.

You get points for your response time, meaning the sooner you tap that dot before it jumps to its next location, the more points you’re awarded. The game has three levels of difficulty – Easy, Medium and Hard. With each of the levels, the size of the dot decreases and the speed at which it jumps from location to location increases dramatically. At the Hard level, you’re well on your way to tapping the screen nervously chasing the ever-smaller white dot.

From FDG Entertainment came another creative and addictive iPhone game that is bound to take its rightful place on many users’ home screens. Parachute Panic is a simple casual game that’s making use of the artistics behind paper-drawn graphics.

The idea behind the game is to use your almighty powers to land as many men that jump from the airplane up above onto the boats down below as possible. These “kamikaze warriors” need to be handled with extra care, as you have to open up their parachute, take care to float in the right direction and keep them from squashing in between helicopter rotors, getting mowed down by UFOs or drowning in the water. It’s no easy task mind you, albeit you’re gonna have lots of fun watching them drift to safety.

Fact. Most kids at and under the age of 9 use old-fashioned coloring books or at the most play games on their parents iPhone. Fact. iPhone SDK programming is not listed as one of their main favorite activities. But Lim Ding Wen from Singapore manages to beat facts and write a free art application for the iPhone – Doodle Kids. The app made quite an impression on users and the Apple approval team, and has had over 5,000 downloads since being launched 4 months ago.

Doodle Kids is a painting app for your iPhone that lets you draw shapes in the screen. Shapes are randomly generated (be it a triangle, square, dot or line), and they follow your finger movement as you swipe the screen, drawing in different colors and different sizes for a beautiful effect. You can clear the screen and return to its blank stage with a shake of the iPhone. By pinching the screen you can change the background from black to different gradients.

With the release of the latest movie in the Terminator series came Gameloft and launched the game version for the iPhone and iPod Touch. And a great job they did, as Terminator Salvation Army for the iPhone has kept us wanting more at the end, topping what we’ve seen so far in graphics and sound effects for third-person shooters in the App Store.

In Terminator Salvation Army you take control of human resistance leader John Connor and even a Terminator named Marcus Wright in an attempt to save humanity from Skynet and its army of Terminators. Although the game does a great job at not giving away the movie plot, you’ll still get to kick some T-1 and T-700 butt.

With Ice Age 3D Dawn of the Dinosaurs Scrat’s Skate Park for the iPhone and iPod Touch, you take control of your favorite Ice Age character (Scrat or Sid) and skate the pre-historic half-pipe in a futile attempt to collect as many acorns or dinosaur eggs as possible. This one was a real brain twister, because our test team couldn’t figure out if the game was still in development, whether they were playing the lite version or they couldn’t get pass the first level. Yes, they collected a lot of acorns and dinosaur eggs. Yes they looked out for icy blocks in the half-pipe. So what else was there?

Well, not much else. Catch some air, do some cool tricks by spinning Scrat around on the skateboard. Your road to pre-historic nothingness will at times be blocked by icy boulders which you either have to avoid or smash through with Buck’s sword, once you collect it.
