There is a very underserved niche on the iPhone, which is games reminiscent of old carnival games and prize games that you would find in a store such as Wal-Mart. Coin Dozer merely exists to serve that genre, and it proves that, even on a mobile platform, where the prizes are virtual prizes, these games are still wildly fun to play. The premise of the game is to drop coins so that the virtual dozer pushes them, and the coins that are already there, towards the edge and hopefully off the edge. You have a limited number of coins, but they regenerate over time. If you are sick of waiting or of coins falling off the side and not counting for anything, read these tips.
When you play Coin Dozer, it might be tempting to drop all four of your coins side by side, in order to push coins faster and to have less coins just stacking up and not falling. When you do this, though, you get more coins dropping off of the sides, and when coins drop off of the sides, they don’t count for anything.
Instead, drop all of your coins smack in the middle of the coin dropping area, stacked on top of each other. Doing this will cause a bigger pile of coins to push towards the end of the platform, avoiding the sides. Also, coins stacked on top of other coins are easier to slide off the edge. This leads to far more coin attacks and massive multi-coin drops, and it becomes easier to shake coins off of the edge after you run out of coins, allowing you to earn coins back rapidly.
Another way to get free coins is simply to circumvent the waiting period for free coins. To do this, go to the iPhone settings and go to date and time. Change the time to a few hours ahead, and go back to the game, and you will have all the coins that would have normally regenerated over a few hours worth of time. Now go back to the settings and set your phone back to the normal time, and all of your regenerated coins will still be there. This trick lets you play as long as you want without any forced breaks due to lack of coins.
