Orchid Tessera

Orchid Tessera is a quiet logic puzzle set in a glassmaker's atelier at night. Every board is a stained-glass window cut into tinted regions. Set one gem in every row, every column and every region, and never let two gems touch, not even at a corner. Each tessera has exactly one solution, and it can always be reached by reasoning alone. No guessing and no pressure: even the timer can be hidden. SIX GALLERIES, 120 TESSERAE Work through Lantern Atelier, Moonlit Orangery, Velvet Observatory, Tidal Glasshouse, Aurora Terrace and Starlight Pavilion, from gentle 5×5 boards to demanding 8×8 windows. Every tessera awards up to three facets: one for solving it, two without the Loupe, three without the Loupe and without a single conflict. DAILY TESSERA A new board every day: 6×6 early in the week, 7×7 midweek and 8×8 from Friday, harder at the weekend. Build a streak, watch the last five weeks fill in as a glass mosaic, and catch up on any of the past six days. STUDIO Set a fresh tessera of any size and difficulty whenever you like, with best times kept for every combination. Every Studio board has a short Tessera Code, so a friend can enter it and play exactly the same window. GEM CABINET Collect twenty-four gem cuts, from the Amethyst Brilliant to the Diamond Jubilee, opened by finishing galleries, earning facets, keeping Daily streaks and reaching Studio milestones. The cut you choose is the gem you set on every board.
