Hi, I am a prolific logic puzzle inventor and author. Puzzlerium is the place to go if you are looking for handcrafted puzzles. You will also find a biannual open competition called Puzzlerium Optimization Championship (details in the following section).
I write grid-style puzzles that are best solved on a piece of paper. Alternatively, you may solve these on an applet, if available.
I recommend puzzles as a stimulating activity, when you are spending more time in solitude, or you are just relaxing in a park. Adequate stimulation of the neocortex through problem-solving is found to promote brain health and aid regeneration of synapses.
