RuniK is implemented entirely as a tapping game. There's no sliding or more complex maneuvers to be done, with again rewards those new to gaming or those older folks that won't spend time to learn complex gestures or keystrokes. Tapping a color once activates it, showing other surrounding blocks that will be removed if you tap again. If you change your mind and think you can draw together a few more distant blocks, you can tap elsewhere on the screen to try something different. Matching blocks are only those that share a side with some block of the same color. White blocks match everything, and you can trigger a special move that matches all blocks of a certain color. If you finish a round with blocks remaining, those become dormant, until you do a match adjacent to them, at which point they regain their coloration. This helps prevent too many dead ends in the game, which also alleviates frustration.
There's nothing about RuniK that isn't easy to like, apart from it displaying ads. If you're not into that kind of thing, you may be put off, but the advertising is pretty innocuous. Stylish, simple, and effectively executed, RuniK is something we'd like to see more of on our Android phone. Sure, we'll eventually see lots of complex and interesting games brought to mobile, but the fun factor of a game like RuniK is extremely high, without demanding a lot from you as the player. If falling blocks and matching three is your cup of tea, definitely grab a copy of RuniK for Android.
