Should be reduced to 50, and level up to 100. ### 4/5 — Awesome fun and frustrating at the same time *2015-12-26, version 1.0* I totally dig this game. I think 3 minutes to find all 100 is quite difficult. I'd like to see a mode where you find all 100 and that's the base time then you try to get the fastest time. You can switch to 3 minute mode for a real challenge. Due to the randomizing this game has mondo replay ability. I say get it now and challenge your friends. ### 5/5 — Brilliant *2015-12-24, version 1.0* Just the right balance between "What the heck?" and "Got it!" Challenging and yet calming. Has a great "One more time. I can do better!" feel to it! ### 4/5 — Cool game. But power up would b nice. *2015-12-19, version 1.0* So far so good. Fun brain training game. Wondering if u all can eventually make an update to this game and have power ups hiding behind random numbers. Like an xtra time power up, or an help power. And to make the game more harder make a level mode like tricky mode. Where some numbers positions are changed to another spot on the board. Or even make an bad power up like a number bomb power up where when found it rearranges all the numbers around. Ps loving the different musics and color themes u can choose from. 😃 ## Frequently asked questions about One To One Hundred ### How high can you count in One To One Hundred?
