Step 1: Bet everything until you reach at least 1600. Restart if you lose everything with less.
Step 2: Hold down the left arrow key and never let go. When it reaches ~20% to bet, press spacebar.
Step 3: If you lose, bet +5% more than last time then press spacebar. With each loss, +5%.
Step 4: If you win, reset it back to 20% bet.
Step 6: Repeat steps 2 to 5.

Eventually, you will get to $1,000,000. Go for as long as you want~
