Sequetur vs Unfoldit

Like having fun with numbers? Sequetur challenges you to complete a series of number sequences and awards points based on the difficulty of each puzzle. Be careful, entering the wrong answer will result in a deduction of a quarter of the puzzle points from your total, but you can skip any puzzle you find too difficult. Hints are provided by showing the number of digits in the correct answer, and presenting 5 digits from which the answer is constructed.
