Summary of "4 Astuces pour Gagner au Chifoumi"

4 Key Tricks to Increase Your Chances of Winning Rock, Paper, Scissors (Chifoumi) up to 80%

The video presents four effective strategies to boost your winning odds in Rock, Paper, Scissors, also known as Chifoumi.

Trick 1: Psychological Suggestion

Remind your opponent not to use the “water well” variant—a common but unofficial addition to the game. This suggestion often leads them to choose rock first, as they consider it the most powerful sign after excluding the water well. You can then start with paper to win the first round.

Trick 2: Avoid Repetition

Statistically, players rarely pick the same sign three times in a row. For example, if your opponent has played scissors twice consecutively, expect them to switch their choice in the next round.

Tricks 3 & 4: Research-Based Predictions from Zhejiang University (China)

These tricks rely on predicting your opponent’s next move based on the outcome of the previous round:

If your opponent won with a sign, they will likely repeat it next round (about a 2/3 chance). Example: If they won with rock, expect them to play rock again.
If your opponent lost, they tend to switch to the next sign in the sequence: Rock → Paper → Scissors → Rock Example: If they lost with rock, expect them to play paper next.

Using this logic, you can choose the sign that beats their expected move, giving you approximately a 66% chance to win.

General Strategy

Combine these tricks for the best results:

Start with Trick 1 in Round 1.
Then apply Tricks 2, 3, and 4 based on your opponent’s previous choices and whether they won or lost.
This approach maximizes your winning chances over multiple rounds.

The presenter encourages viewers to use these strategies for friendly bets, such as deciding chores, and to enjoy bluffing friends and family.
