The odds do change as you flip the coin, in a way. While the odds of selection of any one independent flip remain 0.5, they diminish exponentially with each successive successful selection. In other words, they are 0.5^n where n represents the number of consecutive heads or tails. Put another way, the probability of getting heads 10 times in a row is 0.5^10 or 0.0009765625.
