Diagonal Duel – Game Review
Diagonal Duel is a game from Brian Savidge, first launched in 18th September 2020.
It’s rated 4+ and currently has 20+ ratings on the App Store.
What Makes Diagonal Duel Stand Out
Diagonal Duel against a level 0-100 computer, with two players on the same device, or in ranked online games! Diagonal Two Squared is a game similar to Connect Four but essentially with the board rotated at 45 degrees. This allows for play on two "sides" from the start instead of the original game, on which you only play only along the bottom. The app allows for two players to play on the same device, to select a level from 0 to 100 computer to play against, or to play against random opponents.
This game offers engaging gameplay and regular updates for mobile players.

Player Experience Highlights
Community Insight:
Initially we thought this game was pretty fun and easy to get the hang of but then we quickly became bored. It could definitely use some programming updates, its truly not that engaging or difficult.
How is this not the #1 app on the App Store.
Dan, your positive take on this crafty game pushed us over the edge to download. Its people like you that make this crazy internet obsessed world we live in a little more sane :).
This is honestly the most premier game Ive ever played in our 22 years of existence!! We found ourselves playing this game for 74 straight hours with out blinking an eye. This game is truly revolutionary and we just cant get enough of this game. 2020 just got a whole lot better.
This is an incredible game that brings back the nostalgia of Connect 4 from our childhood. Great graphics and phenomenal execution of software. Would definitely recommend. Would give 6 stars if we could.
Such an insightful take on the classic Four in a Row game. An impressive feat of groundbreaking innovation! Would highly recommend to anyone looking for a new game to play.
This app is thought-provoking. Genius. Brilliant. The critics are raving.
