About this app
TriFace Logic is a 3D logic puzzle game. Fill a 3×3×3 cube of 27 cells with numbers so that every row and column on each outer face follows the rules, until the entire cube is solved. - Place 1, 2, or 3 in each cell; every row and column on all six outer faces must contain no repeats. - Some numbers are given at the start and cannot be changed—use them to deduce the rest. - Switch X, Y, and Z slices to cross-check your reasoning from different angles. - Check and Hint are available when you’re stuck, but solving with fewer assists is more rewarding. - Three difficulty levels—Easy, Medium, and Hard—with fewer givens as the challenge rises. - Your solve time is recorded, with achievements, win streaks, and other long-term goals to chase. A good fit for fans of sudoku and logic puzzles—train your mind in short sessions and enjoy the satisfaction of cracking each cube.
App details
What you can learn from TriFace Logic
Every shipping app on the App Store has gone through the same decisions you're working through right now: which screenshot goes first, what caption sits over it, which device frame to show, what color the background should be. The 4 screenshots above are TriFace Logic's answers to those questions — they're public, they're real, and they made it through Apple's review.
Notice the first screenshot in particular. It's the one users see in search results and on the product page, and it's where most apps spend their best caption and tightest design. Look at the proportion of background to phone, where the text sits, what one thing the image is trying to communicate.
