Chronoku

Chronoku is a free daily history puzzle game. Every day, you get 9 historical events from Science & Tech, Arts & Culture, and World Events. Your challenge: arrange them into a 3x3 grid.

The rules are simple:

• Each row and each column must include one (and only one) of each category
• Events must be in chronological order left-to-right across each row
• Events must be in chronological order top-to-bottom down each column

Place your events, hit submit, and see which ones lock in. The rest bounce back - rearrange and try again. Solve it in fewer attempts for a better medal.

Features:

• A new puzzle every day
• Track your streak
• Share your results with friends
