Four damaged words. Seven glyphs. One signal rapidly disappearing into static. Mind the Signal is a tactile word puzzle built into a pocket-sized communications receiver inspired by the wonderfully overcomplicated technology of the 1980s. Select a glyph. Patch a missing letter. Lock the word. Complete three five-lock segments before the transmission is lost. Simple in theory. So was setting the clock on a VCR. INTERCEPT The carrier is fading and signal strength is always falling. Correctly completed words recover it. Wrong placements add interference. Let the signal reach 0% and the transmission is lost! OPEN CHANNEL The same word-repair system without signal loss. Work at your own pace, recover themed transmissions, and operate an unreasonable number of illuminated controls without an immediate communications emergency. DAILY One shared 15-lock transmission every day. One ranked attempt. No hints. No signal restores. Completion time posts to Game Center, where the permanent record of your radio-operating competence is available for public inspection. RECEIVER SPECIFICATIONS - Four damaged words displayed simultaneously - A seven-glyph repair tray containing answers and decoys - Themed transmissions to recover - Three archive fidelity levels: Recovered, Verified, and Mastered - Ranked Daily play, followed by unranked practice - A persistent archive tracking every recovered signal - Tons of visual customization to fine-tune the receiver to your specifications Mind the Signal is free to play. Optional rewarded ads can bank hints or restore a failed signal. Occasional interstitials appear between rounds. Turns out that communications infrastructure is not free. The one-time Operator Upgrade removes every ad, starts each new Intercept or Open Channel with up to four hints, makes the once-per-run Intercept restore immediate, and expands receiver customization to 100 style combinations The words are incomplete. The carrier is fading. You are now on shift.
