Masyu: Line Logic

Masyu: Line Logic base game on Steam US: $2.99, advertised 40% off; checkout not tested.

Masyu: Line Logic is a single-player loop-drawing puzzle game in which black and white circles constrain how a line passes through a grid. White circles require a straight passage with a turn beside them, while black circles require a turn followed by straight segments on both sides. The aim is one continuous loop without branches or crossings, rather than filling every cell or guessing a hidden picture. Its daily puzzle has a catch-up calendar, and Endless mode supplies 15,000 boards across four sizes and four difficulty levels. A tutorial, gradual hints and mistake checking help explain the next logical step; mouse and keyboard controls, undo, optional timers and display choices support different solving preferences. Steam lists a Windows release with a minimum 64-bit dual-core SSE4.2 processor, 2 GB RAM and graphics supporting OpenGL 3.3 or DirectX 11. No detailed recommended profile or Mac entitlement is listed, and these published requirements do not establish tested frame rates. The exact named standalone Steam purchase displays USD 2.99 against the seller reference USD 4.99, advertised 40% off. This is a seller comparison, not an independently tracked historical low. Checkout and redemption were not tested. The current standalone promotion ends 2026-11-19T18:00:08+00:00.
