The challenge mode unlocks after you have completed all of the quests in the Hatchville County Fair quest sequence. In the challenge mode, you’ll compete against other players to see who is able to collect most horseshoes by playing levels in the challenge mode quests. To start competing, complete a level in the challenge mode.
You’ll be offered one quest at the time, and after you have completed the quest, a timer will count down to the next quest. You can choose to unlock the next quest right away with coins.
Each level in the challenge quests will reward you with horseshoes. The amount is tied to the amount of coins you earn on the level. Additionally, you’ll receive horseshoes for each completed quest. You can see your horseshoe count below the lives counter in the upper left corner, and your current ranking in the challenge on the trophy that appears in the event area.
You can see your horseshoe amount and ranking also on the challenge mode leaderboards. The leaderboards also display the rewards for each ranking. The higher you climb on the leaderboard, the better rewards you can win.
The challenge mode reward will be given out once the County Fair event ends. To claim your reward, tap the trophy in the County Fair area.
