Close your eyes. Drag through a black screen by vibration alone, past walls and traps you never see, to the exit. A new Daily level every day, the same for everyone. The screen is black. Somewhere in the dark is an exit, and between you and it are walls and traps you can't see. Put your finger down at the bottom edge and drag. Your phone tells you the rest. Thrum is a puzzle game you play by touch. Lift your finger or touch a trap and the run is over. Reach the exit and the hidden map lights up, with your path drawn across it. You can play it with your eyes closed. HOW YOU FEEL THE DARK • A hum grows stronger the closer your finger gets to a hazard • A dull hum is a wall, a crisp one is a trap • A beat quickens as you close in on the exit • Bump too many times and the run ends THE DAILY One level a day, the same for every player in the world. It flips at 08:00 UTC, and your first attempt is the one that counts. • A daily Game Center leaderboard: your time plus a penalty for every bump • Streaks that grow with every day you escape • Share your result without spoilers: an emoji ladder of the rows you climbed, and a card of the board still under fog CAMPAIGN Learn to read the hum, trust the beat and stop touching the traps. A short tutorial teaches the whole game in three steps, then Chapter 1 gives you ten levels free. Escape without a single bump to climb the Clean Runs leaderboard. PRACTICE Endless levels, as many as you like. Hit New and go again. BUILT FOR EVERYONE Thrum is played by feel and sound, so it works for blind and low-vision players too. • Sound mirrors every vibration; it follows your ringer switch, or turn on Sound when silent • Spoken cues and VoiceOver support • Forgiving lift, a stronger faint hum and an always-visible start strip • Accessibility options are never locked behind a purchase • No ads, no accounts, no tracking THRUM PRO One purchase, no subscription, and Family Sharing is on. • Three more chapters, 30 levels: Dark (the exit moves down the board), Deep (the exit could be anywhere) and Keys (find the key before the exit) • The Practice Lab: set the board size, hazard density, sense radius and bump limit, and replay any level by its code • Stats: your runs, escapes and bumps over time The Daily, Practice, Chapter 1 and every accessibility option stay free. Thrum needs an iPhone with haptics.
