## What is Brain Spark Puzzles?

Brain Spark Puzzles is a puzzle game that packs four classic puzzle types into one app.
The rules are simple, and you can enjoy one stage at a time, whenever you have a moment.

PUZZLES
Crowns (Logic):
Place one crown in each colored region. Crowns cannot share a row or a column, and they cannot touch each other, even diagonally. Use the clues and solve by reasoning.

Color Link (Space):
Connect each pair of matching numbered dots with a line. Lines cannot cross, and every cell must be filled.

One Stroke (Foresight):
Starting from 1, visit every cell in a single stroke. Plan ahead to find the path.

Calc Blocks (Math):
Use the number on each bold frame as a clue and fill in the digits. No digit repeats in a row or a column.

FEATURES
- 4 puzzle types x 100 stages each = 400 stages. Boards grow gradually and get harder
- Earn up to 3 stars per stage, and aim for the target time
- Your titles rise (Apprentice to Grandmaster) as you clear stages, with rewards such as background colors
- Unlimited undo and restart, free
- Hints show you one correct move when you are stuck
- Play offline. No account needed

NOTES
- Free to play. The app shows ads. When you run out of hints, you can watch an ad to get more.
