Farm Mahjong 3D is a three-dimensional block-matching game. Against a grass lawn, the player must remove pairs of farm- and outdoor-themed wood blocks from stacks across levels before time runs out. Their goal is to try to reach the highest level and score possible while a six-minute timer counts down to zero.
The game displays a different stack pattern on each level. The icons on the blocks also change from level to level. For example, patterns typically display a mix of farm products (i.e., bread loaves, cheese wheels and milk bottles); animals (i.e., livestock, pets and wild animals); garden items (i.e., harvested fruits, nuts and vegetables or tools); natural elements (i.e., sun or water); and even structures (i.e., different colors of barns and sheds).�
When the player selects a pair, the blocks appear near the score in the upper-right corner before disappearing from the field. If the player can't find a matching pair, they can rotate the stack side to side and up and down for a better view. They can also reshuffle the blocks with a Shuffle tool in the lower-left area and remove a pair automatically with a Hint tool in the lower-right area. They must watch ads to continue to use these tools.
Farm Mahjong 3D offers several bonuses. If the player matches a pair every three seconds, they receive a X2 point bonus. They receive X5 for matching the same icons consecutively. Lastly, they receive a +0.05 time bonus for finishing a level.
