The original best-selling mobile word game, reimagined! Pick your words wisely! As you play, more tiles rise from the bottom of the screen! It'll take all of your lexicological wits, and tactical know-how to keep your columns down. If any letters make it to the top row, it's game over. Classic modes Daily Tower, Tower, Puzzle, Rush and Zen are all back and packed with brand new BONUS TILES that double (or more!) word values. Joining them is the brand new Search mode, plus ExPuzzle, Double Puzzle, Bubble Puzzle, and Blitz mode! That’s eleven modes in all! Plus iCloud Backup, Highscores reported for games even while in-progress, detailed statistics for every mode, Game Center leaderboards, and achievements. ————————— It’s pretty wild to be revisiting my first hit game, SpellTower. I can't believe it's almost 10 years since it released. The first iPhones it ran on had a 3.5 inch screen and 320 x 480 resolution! I literally did a double-take at that resolution when I looked it up. A funny part about having a hit game is people talk to you about it. With SpellTower I heard about grandparents playing the game every morning to keep their minds sharp, parents playing it with their kids, expectant mothers playing it to get through morning sickness, and countless sightings of strangers playing it on subways, planes — even elevators. I got into games because I wanted to connect with people in a positive way. I wanted to help people think critically and come away with more than they arrived with. Games felt like a way to do this on a huge scale, but the stories I heard from SpellTower players taught me that games do so much more for people than I ever expected. I’m deeply grateful that SpellTower has been able to be something special for so many people, and I think that’s why so many people have shared it with friends, loved ones, and strangers on elevators. Even though SpellTower is a game I made, it’s really barely mine anymore. The experiences and love I had for the game has been outstripped by its audiences a thousandfold. I thought a lot about all the experiences that people have had with the game when I was designing this new version. I hope it gives everyone who’s loved the game a reason to pick it back up again and share it amongst their friends and family. -zach

Knotwords+ is a minimal and elegant logic puzzle — with words. The rules are simple: arrange the letters in each section so every word is valid, across and down. Each puzzle may seem difficult at first — but like all my favorite newspaper puzzles, it gets easier as you progress. Each step guides you naturally towards the solution. This is the kind of game I've been trying to make my whole career — I'm amazed Jack and I discovered this design. We hope you like it.
