Player story: Gêmeos Investem bet R$ 10 per day on Fortune Tiger for 30 days — declared loss of R$ 64.12

The story

The hosts of the channel Gêmeos Investem proposed a challenge recorded on video: betting R$ 10 per day for 30 days on Fortune Tiger, an online casino game popularly known as Tigrinho. The stated goal was to observe the outcome of daily bets over the course of a full month, totaling a planned turnover of R$ 300.

At the beginning of the video, published on 23 August 2024 and running 24:08 in length, the authors explain that they deposited R$ 300 into a gaming account. According to them, this was the minimum amount needed to cover R$ 10 in daily bets for 30 days. Shortly after the deposit, the displayed balance showed R$ 600 in the account after depositing R$ 300, due to a bonus granted automatically. According to the hosts, only the R$ 300 deposited was their own money.

On the first day, according to the authors, the bet was set at R$ 0.40 per spin, which resulted in 25 spins to complete the daily quota of R$ 10 as planned in the challenge design.

Regarding the bonus received after the deposit, the authors stated that the bonus cannot be withdrawn and only gets in the way. «serve pr você perder exato você não consegue sacar não muda nada só te atrapalha esse bônus» (04:49), they said during the video. In the hosts' assessment, the amount credited as a bonus had no real use, as it could not be converted into a withdrawal.

On the third day of the challenge, the authors recorded the session balance: bet R$ 10, won R$ 1.20, loss of R$ 8.80. According to them, the return that day fell short of the amount wagered.

Later in the challenge, the hosts report having achieved a positive result in a daily session for the first time: R$ 2 in profit. «finalmente ficamos R 2 Positivo depois de sei lá quantos dias» (16:11), they said. According to the account, it was the first session throughout the month in which the day's return exceeded the bet amount.

On the last day of the challenge, according to the authors, the account balance stood at just over R$ 235. The accumulated declared loss at the end of the 30 days was R$ 64.12, an amount that represented, according to the hosts, more than 20% of the deposit.

At the close of the video, the authors addressed viewers directly with a message about the challenge's outcome: «qual que é o recado final que fica para você não Aposte o seu dinheiro você vai perder» (23:42).

The numbers of the session

The table below compiles the values declared by the authors throughout the video. The central figures are the R$ 300 deposit, the R$ 10 daily bet, and the declared final loss of R$ 64.12.

What the maths expected

Fortune Tiger has a declared RTP (return to player) of 96.81%. The house edge corresponds to the complement of the RTP: 3.19%. This percentage represents the fraction of each bet that, on average, over a very large number of spins, stays with the house.

The declared turnover in this challenge was R$ 300, consisting of R$ 10 bet per day for 30 days. At R$ 0.40 per spin, the total is equivalent to 750 spins, or 25 per day. The mathematically expected loss for this volume of bets is R$ 9.57 — the declared turnover multiplied by the house edge.

The result declared by the authors was a loss of R$ 64.12, a value 6.7 times greater than the expected loss and equivalent to 21.37% of the turnover. This difference, although substantial, is not uncommon in small samples.

The R$ 300 turnover is what the authors declare as the test design, not a value verified by third parties. The RTP is a long-term average, calculated over hundreds of thousands or millions of spins. The equivalent of 750 spins constitutes a tiny sample compared to that universe. In samples of this size, it is ordinary for the result to deviate significantly from the theoretical average, in either direction. A result several times above the expected loss — or even a gain — is ordinary variance in a volatile game and does not constitute evidence of manipulation or of a period when the game pays more or less.

What this story does not prove

The values presented in the video are self-declared. The R$ 300 deposit, the final balance, and the R$ 64.12 loss appear only in the authors' account, without independent verification through bank statements or audited records. The real bankroll was not verified. The video captions are auto-generated and may contain transcription inaccuracies.

The challenge covers a single game, Fortune Tiger, and a single 30-day period. The behavior observed in the equivalent of 750 spins of a specific game cannot be generalized to other casino games, which have distinct RTPs, volatilities, and mechanics. A test is one sample among many possible ones: it does not prove that the game pays out nor that it is rigged.

The video mentions a bonus that resulted in R$ 600 in the account after depositing R$ 300. The terms of this bonus are known only as the authors describe them in the video — according to them, the bonus cannot be withdrawn and only gets in the way. It is not possible to confirm the exact rollover or redemption conditions without access to the terms applied by the betting operator at the time of the deposit.

The result of a single test — whether a loss or a gain — does not constitute statistical proof about how the game functions. For a conclusion to have statistical significance, a volume of spins incomparably larger than the equivalent of 750 spins in this challenge would be required.
