Put the first euro exactly in the middle of the table. Place each next coin "mirrored" to the coin your opponent has just placed: draw an imaginary line from the last coin of your opponent, through the center of the table, and place your coin on that line, exactly as far from the center of the table as your opponent's coin. In this way, you are sure that you can always place a euro and that your opponent is the first one that can no longer place a euro.

132
2 (+13), 15 (13+13), 41 (+13+13+13), 80, (+13+13+13+13) 132
2 (Count the number of closed loops)
eg: 8 would have 2, 6 would have 1, 0 would have 1, 00 would have 2.
When it is 15 minutes into 24 hours.
1 + 1/3 + 1/5 ... + 1/(2N-1).
Each time you tie two together the number of string ends available decreases by 2. The chance of grabbing a string and its end is 1/(2N-1).
Any number.
Mosquitoes. They add to misery, subtract from pleasure, multiply quickly, and divide your attention.
13
because 7+7=14 and 14-1=13
LOL.
101 x 5 = 505 which looks like SOS,

101 x 7 = 707 turn upside down and it becomes LOL.
