How to bet on horses racing

Do you guys know how to bet on horses? I'm planning to try playing this horse racing betting soon.

There are too many factors to consider when betting:
1. Horses' running mood
2. Jockey
3. Weather condition
4. Handicap
5.Owner's instruction
6.Trainer
7. Betting returns.

My opinion: don't waste your money betting on horses.

Hello Lucky Plus,
1.Do not bet on every race.
2. Bet on the Wining jockey, Do research and find out. He will only be riding 3 races
3. Bet on him, He has to keep his ranking or his ratings will drop.
4. The best jockey gets the best horse.
