The number of games you should bet on is not a one-size-fits-all answer, as it depends on various factors including your betting strategy, risk tolerance, bankroll management, and the quality of the odds available. Here are some general guidelines to consider:

1. **Bankroll Management**: A common rule of thumb is to bet only a small percentage of your total bankroll on any single game. For instance, many professional bettors suggest risking no more than 1-5% of your bankroll per bet. This helps ensure you can survive losing streaks without depleting your bankroll.

2. **Risk Tolerance**: Your personal risk tolerance will also play a role. Some people are comfortable making more bets, while others prefer to be more selective.

3. **Quality of Odds**: It’s generally better to bet on games where you believe you have an edge. This might mean betting on fewer games if only a few offer favorable odds.

4. **Knowledge and Research**: Bet on games that you are familiar with or have thoroughly researched. Betting on too many games without adequate knowledge can lead to poor decision-making.

5. **Bet Selection**: It’s often better to be selective and only bet on the games where you have the most confidence in your pick rather than spreading your bets too thin across many games.

6. **Time and Effort**: Consider how much time you can dedicate to betting. Betting on too many games may require a significant amount of research and tracking, which might not be feasible if you have limited time.

As a starting point, you might consider betting on just a few games that you feel confident about. As you gain more experience and become more familiar with the betting process, you can adjust the number of games you bet on accordingly.

Remember, responsible gambling is key. Only bet what you can afford to lose, and never chase losses by placing more bets than you initially planned.
