We give you a grid, we give you a crazy rule, & we give you some values. All you have to do is look hard at the grid & find which row or column has that value for the given rule. Easy as you like it. And then you just have to do it for 99 more times. So, sharpen your brain, sharpen your eyesight, sharpen your reflexes & bring it all together to quickly scan the grid in different directions & find the correct answer before the timer runs out! Try out a game with a unique gameplay & challenge yourself to reach the summit of 100 Rounds with the rules becoming more crazier & wackier with each passing grid. We promise you would never have played anything like this! Deep dive into the game & see how far you can make it before a mistake sends you hurtling back to the start. Along the way, you will encounter all different kinds of shapes, numbers, letters, boxes, clocks & what not. There are no Worlds, no Levels, no Difficulty Settings, no Boosts, no Bonus, no Achievements. An uncomplicated game with just one singular objective & that is to complete all the grids. And also just pure fun. * Unique gameplay which is a twist on the grid search puzzles. * Pick up & Play. One touch Gameplay in Portrait mode. Just swipe to mark the correct row/column. * Over 70 different types of rules for you to figure out. * 4 different types of aids/power-ups available for use. * A cute way of visually depicting the progress in the game through the growing moustache of Mr. Mustachio's character. * Uncomplicated game with a single objective to complete all the rounds. * Leaderboards to show where you stand in the charts. * Comprehensive Statistics to give a glimpse how well you have been playing the game. * Single Player & works offline. Mr. Mustachio builds upon the gameplay of the evergreen word search puzzles & puts a little spin on that!. Use your power of observation to search the grid for the row or column which matches a given rule & a corresponding value! Of course, we added a time limit & threw in some colours to make things interesting! The character of Mr. Mustachio adds a fun dimension to the game! Watch the moustache grow with more grids you figure out! Here is a small silly poem explaining the moustache :) "An egg shaped guy, extraordinary is his panache, Always smiling, as he twirls his magnificent moustache! With a grid of blocks, he tests your skills, Fast reflexes, quick thinking, needed in this game of thrills! Mr. Mustachio needs your help, truth be told, The span of his whiskers, the grid controls! Add, Subtract or Multiply, do the proper math & make his handlebar grow, Diamonds will be your reward, as you chase your high score!" Maybe you like math. Maybe you like to do brain training exercises. Maybe you like to test your reflexes. There is something for everyone in this small & simple, yet quite fun & challenging game. Enjoy! ********************************* If you like playing the game, please consider leaving a rating. If you want to drop some feedback, please do so at contact@shobhitsamaria.com!
