For puzzle lovers seeking fun and challenge, Dot Knot offers a minimalistic and elegant design with daily and friends challenges. Gameplay includes cross-paths and multi-color dots to increase the complexity within the levels. Use "Pauses" to buy time and think over the solution & "Hints" if you ever get bogged down while completing game levels.
The history of these types of puzzle games is very interesting. In 1932, a book titled "Puzzles and Curious Problems" by Henry Ernest Dudeney introduced these type of puzzles. Various variations of these puzzles are now available on App Stores.
