Reach 100 – a (unsolvable?) puzzle game▲13
I recently remembered a game we used to play with pen and paper some 20 years ago, where you need to fill a 10x10 grid writing numbers in the grid up to 100 following 2 simple rules. After showing it to my kids I thought it would be nice to adapt it digitally so that they could play it more often (not needing to draw the grid etc.) and so that other people could play it as well. What I'm really interested in with this submission (beyond general feedback) is wether anybody knows the origin of the game and if it's solvable. Because that's the catch, my highest score of all time is 97 and it…

I made a word building game supporting anagrams and one handed use▲29
Hi everyone, Wanted to share a game I built. It's called Unscramble! and I believe it's the simplest word building game. Rules: You get a few letters on screen. You need to make one word with all the letters. Tap a letter to select. Tap again to deselect. Faster you go, better you score. If you enter anagrams of the word it's looking for, it gives you extra points. If you are stuck, you can either "Ask Friend" or get Hint. You get extra points for getting the word fast but you don't get penalized for taking too long. I believe the simplicity of the game along with big touch buttons makes it…
