** Only 43 moves ** Solution to MS Solitaire Collection, Daily Challenge, 1/17/2018, Spider, Earn a score of 700 Here are the results of my priceless competitors: Joe Bot - 64 moves Zeming Jin - 58 moves Voranc - 58 moves My solution is irrefutably the most efficient. Note: You have to do a little math to obtain the move count. And be aware that the application doesnt count the move that completes a stack. Let A2 be the initial score. Let B2 be the final score. Let C2 be the number of stacks completed. The Excel formula is: A2-(B2-(C2*100)) So, in this case, 500 - (757 - 300) = 500 - 457 = 43
