How about some free games to help make the last work day of the week a little easier? We’ve got a 2D ninja platformer that’s extremely easy to play in Chop Chop Ninja, a goofy casual action game starring Sir Isaac Newton in Newtonize, and a sequence counting game that’s simple but addictive in Twenty-Five. Best of all, they won’t cost you a dime, digital or otherwise. Check them out below.
Chop Chop Ninja (iPhone) Free (was $0.99)
Simplicity of controls is part of what makes Chop Chop Ninja a pretty great little iPhone 2D platformer. As a ninja, you have to save your love by gathering special ingredients — she’s been transformed into a jade statue, and only a certain potion can save her. For some reason, samurai are standing in your way, as are lots of wooden boxes and other obstacles for you to traverse.
The controls are so simple because while Chop Chop Ninja employs the iPhone’s touch screen, it doesn’t actually use buttons. Touch anywhere on the screen to make your ninja move there — touch above him to make him jump, and tap behind enemies to make him fight them. It’s easy but engaging, with a great art style and a lot of fun to be had.
Newtonize (iPhone) Free (was $0.99)
Isaac Newton is under attack: evil gravitons (or… something) are after the famed scientist, and he’s retreated to the roof of his home to fight them off, but all he has are apples, quick feet, and the aid of gravity itself.
As Newton, you use touch controls in this casual game to aim and drop apples on the gravitons to destroy them. The goal is to prevent them from reaching the top of the building. You rack up points as you take out the evil guys, which rise from the street level and move in different pattens to attempt to confound you, and Game Center support lets you log scores on leaderboards and earn achievements.
Twenty-Five (iPhone) Free (was $0.99)
A sparse, super-simple but challenging game, Twenty-Five has just one style of play. The game puts a sequence of numbers on the screen in tiles, and you need to tap the numbers in sequence to eliminate them. The idea is to count through all the number tiles, which have different colors, as quickly as possible. It’s a really simple idea, but grows to be fairly challenging.
With three different difficulties, Twenty-Five has a tendency to get you to keep playing it, always trying to improve your score. The easiest difficulty keeps the different colors minimal, while the hardest scatters colors through the grid of tiles to make it more difficult for your brain to quickly find the next number in the sequence. For free, Twenty-Five is an interesting way to kill time as well as a tough challenge.
