Spin Wheel

I failed whilst playing level 2939 with just 1 move away from completion and was offered to win moves by spinning wheel. I spun the wheel and it landed on either a jellyfish or lollipop hammer. I was then shown the spinning wheel display for another chance to get extra moves in exchange for 7 gold bars. I was unsuccessful and gained 2 color bombs instead. I spun the wheel again hoping to get just 5 extra moves to finish the level but I ended up with a lollipop hammer which did nothing to help. This went on a total of 9 times costing 7 gold bars per spin until I eventually got what I wanted: 5 moves. I spent 63 gold bars, a very hefty amount, and received, I believe, 6 color bombs, 1 jellyfish possibly, 4 lollipop hammers just to score 5 more moves. I realize this bonus item, which comes in handy when needed, may or may not be available to every player but if it is a wheel that a player spins to win extra moves why litter it with boosters. This actually defeats the purpose when the player is paying 7 gold bars each spin for the opportunity to win moves. What is a player to do - continue to spin, cross fingers and spend gold bars until the arrow finds its mark? Please review and revise. Thank you.
