Crossdigit vs Hook Chain

Crossdigit is a math crossword-like puzzle game. Every clue is an equation; every answer is a number. ------------------------------------------ HOW TO PLAY Each numbered entry is a small math problem - 12 + 7, 84 ÷ 6, x² + 5 = 30 - and the answer are the digits you write into that row or column. Crossing entries share a digit, so a confident answer unlocks more clues. ------------------------------------------ FOUR DIFFICULTIES • Easy - addition and subtraction. • Medium - adds multiplication. • Hard - adds division. • Extreme - algebra: linear, quadratic, and mixed equations to solve for x. The grid size and answer-digit range are sliders you control. Start with a 6×6 grid of two-digit answers; ramp up to a 13×13 grid of five-digit algebra. The puzzle generator makes a unique puzzle every time. ------------------------------------------ DESIGNED FOR EVERYDAY LIFE • Plays fully offline once installed. • Pause anywhere - the timer freezes when you switch apps and your puzzle resumes exactly where you left it, even after a force-quit. • Light and dark themes that follow your system. • No accounts required. A device-private ID lets you sync your stats and earn a leaderboard rank without giving up an email. ------------------------------------------ LEADERBOARD AND DISPLAY NAMES Finish a puzzle and your time and score are weighed by difficulty and grid size. Faster solves of harder puzzles outrank slower solves of easy ones. Claim a globally-unique display name (changeable every two weeks) to stake your claim on the global board, or stay anonymous - your choice. A linking code lets you bring a second device into the same account without an email or password. Generate a code on one phone, redeem it on the other, and your stats merge. ------------------------------------------ WHY MATH CROSSWORDS? Crossdigit puzzles teach you to commit and verify - write a confident guess, see what you get correct and adjust. Work your brain out with some mental math. ------------------------------------------ PRIVACY Crossdigit requires zero login. Anonymous gameplay uses a device-private random ID; the optional display name is the only thing other players ever see.. ------------------------------------------ Get it and get solving today!
