Get all your counters down the cogs but watch out, a wrong turn could lead to your downfall! Use your key to turn the cogs, but look out - if a cog already has your opponent's key in, you'll have to wait until they move their key before you can turn that cog! Try playing with an added twist - getting your counters down in colour sequence. For a greater challenge, try to get your counters down in colour and number sequence! It'll have you wanting to try again and again! Whatever game you play, if one player keeps winning, you can change their cogs to even the odds.
