to prepare a contest I need several days because the puzzles are selcted one by one to find the one with assigned difficulty and, notwithstanding the several controls sometime I cannot avoid mistakes.
that is why I thought to an additional contest with no selection of the puzzles and difficulty at random, where there is very little work for the preparation.
the difficulty may vary from easy to hard, that is why the name I choose is "ROULETTE"
the contest will be played each 4th friday and saturday of the month.
