Balloon Survivor

The Balloon Survivor is one of the hardest games to finish, with a chance of completing it (without lifelines) equals 1 to 362 880. The game is easy to play with simple rules. To complete the game you will need to finish all of the 8 rounds. In each round you need to select a balloon number between 1 to 9.
At the start of each round the balloons will start rising towards the needles. They will pop one by one until the last one remains. If the last balloon number is the one that you've selected, you complete the round and that balloon will not be included in the next round.
In order to finish the game you must reach the last round. There you will have only two remaining balloons and you have to successfully guess which will be the last remaining balloon.
You will have three lifelines at your disposal. You can access them only from round one to round six.
The lifelines are:
1. Skip round - You can use it only one time.
2. Two numbers selection (you can select more than one number for a round) - you can use it 3 times.
3. Repeat round - you can use it 3 times.
