Open a room. Solve it slowly.

Solvizz is a cozy region-division puzzle set inside a paper-warm mind palace. Nine brain zones wait in the dusk, each holding a grid of rooms that haven't yet decided what colour they are. To wake the palace, you divide those grids into regions — one careful click at a time — until every region obeys the law of the lobe it lives in.

There is no timer. There is no fail state. Every wrong click un-clicks in a stroke. Every violated rule tells you which one, in its own colour. This is a game for the evening after the world has stopped shouting.

How it plays

• Divide, don't fill. Each puzzle is a small grid you partition into contiguous single-colour regions. Every region must satisfy the rule cards beside the board — sometimes one card, sometimes four at once.

• Eight lobes, eight laws. Hippocampus frames the board in a colour that appears nowhere inside it. Cerebellum wants every region the exact same size — Parietal wants every region a different one. Occipital wants every region the same shape; Frontal wants no two alike. Temporal weighs every colour equally. Brainstem runs every colour through every row. Amygdala counts the regions exactly. Each lobe owns a signature rule no other lobe is allowed to use.

• 22 rules, 95 combinations. A law rarely arrives alone. The lobe's signature meets a second rule, then a third, and the same small grid starts asking a completely different question. 95 distinct rule stacks across the game, up to four cards on a single board.

• Then the central door opens. Once every lobe is complete, the door at the heart of the mind palace opens onto the Corpus Callosum: 120 crossings on a rule family of their own, where a region's colour is its size. Every one of the 120 is proved to have exactly one solution, and every one can be reached by deduction alone — you are never asked to guess.

• One last room. Behind the final door sits a single 14×14 grid in five colours. There is only one, and it is the only board in the palace that uses a fifth colour at all.

• Rule cards teach themselves. Every rule ships with an inline ✓ Allowed and ✗ Not allowed diagram, tinted to the region you're playing. You never need a manual.

• Snap and settle. Every action lands with a firm click and a soft settle. Nothing lingers, nothing rushes.

Features

• 921 hand-tuned puzzles — 100 in each of the eight lobes, 120 Corpus Callosum crossings, and the one board waiting behind the final door.
  

• 22 rules across 95 combinations — every rule taught on its own card, every puzzle machine-verified as solvable before it shipped.

Inspired by the flat warm-paper geometry of Is This Seat Taken?, the calm system-state cadence of Mini Metro, and the branching beauty of a real neural connectome.
