A machine-shop theme for Solvizz. Brushed metal, square machined corners, rivets at every edge and diamond plate under the grid — with amber strobes for rule violations and sparks on every solve. Cosmetic only: every puzzle, rule and solution stays exactly as it was.
The palace, machined.
Cold Steel strips the paper away and bolts the mind palace to a workbench. Cells square off to a hard zero-radius corner with an outer bevel and a rivet at each one; brushed-steel grain runs horizontally under the paint. Hex bolts, hazard chevrons, gear teeth and rivet heads mark the corners. Locked rooms are bolted shut.
Nothing softer about it. Just the grid, the rules, and a great deal of steel.

What it reskins
- The board. Welded diamond plate inside an angle-iron frame, rivets at every corner, and a spark where your cursor lands.
- The palette tray. Every swatch wears the theme's surface and its own motif, so a chip previews exactly what a click will paint.
- The connectome map. Spines, node collars and the region rail take on the theme's material and hardware. Region colours stay exactly where they were.
- And everywhere else. Navigation rail, tooltips, dialogs, the opening and closing cinematics — the whole palace, not just the board.
Good to know
- Cosmetic only. Not one puzzle, rule, solution or achievement changes. Nothing here makes anything easier or harder.
- Switch whenever you like. Settings → Display → Theme, mid-puzzle if you want. Your progress is untouched, and the original paper look is always one click away.
- Steam Deck ready. Drawn for the 1280×800 handheld screen and the 1920×1080 desktop window alike, with full reduced-motion support.
- Requires Solvizz. This is a theme for the base game — on its own it does nothing.
Nothing softer about it. Just the grid, the rules, and a great deal of steel.
