When we are bored and do not have anything to do, we usually play with whatever we can get our hands on to. Back when I was still in high school, when we did not feel like listening to the class, we usually played games on paper. A lot of games can be played on paper.
There's the famous tic-tac-toe. Where we just need a piece of paper, pens and your ability not to snicker because your teacher might catch you playing. Then we just pass the paper back and forth until all the pages is covered with O and X. With our version of tic-tac-toe though, we do not just use a 3×3 grid. We make use of the entire paper. The bigger the paper the better so we can play the game until the end of the class. We do not even use O and X sometimes, we use S and O. So we called our game not tic-tac-toe but SOS. Works the same way with tic-tac-toe though.
Then there's the game of hangman. This is good for two or more players. While the other player is thinking of a word, the others will try to guess the word one letter at a time. The number of letters in the word are represented with dashes on the paper which the other players will try to complete. With every wrong letter guessed, you draw the figure of the hangman one stroke at a time until such time that the entire picture will be drawn which marks the end of the game. Then you take turns.
We were a bunch of misfits in High School and luckily for us, we were still able to finish without being sent to the dean's office. We do not usually listen to our teacher when it's time for Physics or Chemistry class. What we do instead is bringing a deck of cards to school. Yes, we play card during class. We play the game of Lucky 9. This is more or similar to the card game Baccarat. You just need to draw a hand that totals to 9. Once you have the Lucky 9 card, then you get to enjoy having the pot money.
Those were the days of youth and delinquency. When my friends and I get the chance to see each other, we never fail to play the game card of Lucky 9. It's not that we were bad kids. It's just that sometimes kids just want to have fun.
