About GridSpark (Zalize)

GridSpark follows the queens-style rules that LinkedIn's Queens made popular, marked with crowns: one crown in every row, every column and every colour region, and no two crowns may touch, not even at a corner. GridSpark says it is an independent game, not connected with LinkedIn.

Tapping a cell cycles it from empty to an X mark to a crown, so you can rule cells out as you go. Clashing crowns light up red, and the board is solved when every crown is in place; your solve time is your score. Each daily board is checked to have one solution reachable by a chain of logic, with no guessing or backtracking.

Size climbs through the week: 7x7 on Monday and Tuesday, 8x8 mid-week, and 9x9 or 10x10 at the weekend. A colourblind mode lays a different texture on each region, and a practice mode gives unlimited extra boards outside your streak.

Zalize Daily Games, at daily.zalize.com, is a free set of small browser games from zalize.com, each with one puzzle a day that is the same for every player in the world. All of them switch at midnight UTC. There is no account: streaks and statistics stay in your browser and can be moved to another device with a sync code, and playing every game on the same day earns a Perfect Day badge. The site is offered in ten languages.

How to play GridSpark (Zalize)

1. Open daily.zalize.com/gridspark to load today's board.
2. Tap a cell to cycle between empty, an X mark and a crown.
3. Place one crown in every row, column and colour region.
4. Keep crowns apart: none may touch, even diagonally.
5. Place the last crown to stop the clock.

Tips

• Mark X around every crown at once to see what is left.
• Small regions have few options; settle them first.
• If two regions are confined to the same two rows, no other region can use those rows.
• Turn on the colourblind textures if regions are hard to tell apart.
