Happy Trucks is a filling puzzle game. Your job is to fill up the trucks with liquid. Do that in all 30 levels. For each level there is a different truck, so you need to estimate how much fluid will fit in that truck. You should not overfill the truck, nor should it be half empty. If you make a mistake in the assessment you will start playing that level again. Very interesting game that you will enjoy playing.

Happy Trucks is a filling puzzle game about judging capacity. Across 30 levels, you tap to play, fill each different truck with liquid, and try to land between too little and too much, because a poor estimate sends that level back to the start.
Happy Trucks is described as a filling puzzle game built around one clear challenge: put liquid into a truck until it is properly full. The source says there are 30 levels, and each level uses a different truck, so the amount that worked before may not fit the next container. The listing places it in the Puzzles category with Cool, Funny, Hypercasual, Kids, Puzzle and Truck tags, which fits a simple estimation game rather than a complex driving simulation.
Your goal is to fill every truck with liquid across all 30 levels. Because each level presents a different truck, you need to estimate how much fluid will fit. A successful fill avoids both mistakes named in the description: overfilling the truck and leaving it half empty.
1. Start a level and look at the truck shape before assuming how much liquid it can hold.
2. Use the supplied instruction: tap on the screen to play this game.
3. Fill the truck with liquid while judging the capacity of that level's different truck.
4. Aim for a proper fill: do not overfill the truck, and do not leave it half empty.
5. If your assessment is wrong, expect to play that level again; continue working through all 30 levels.
The only supplied control instruction is: tap on the screen to play this game.
The interesting part is estimation under a changing container. Since every level brings a different truck, the puzzle is not memorizing one perfect amount but reading the new shape and judging where “full” should be. The description sets two failure boundaries at once: too much liquid overfills the truck, while too little leaves it half empty. A mistaken assessment restarts that level, so each attempt becomes feedback for the next try.
Progression is stated simply: there are 30 levels, each with a different truck, and a mistaken assessment repeats the current level rather than moving you forward.
The supplied dimensions are 720 x 1280, which indicates a portrait-oriented playfield; no other device behavior or requirement is stated.
Within Puzzles, Happy Trucks fits a light hypercasual estimation style: a simple input, a clear success boundary, and short retry-friendly levels. The Kids, Funny, Cool and Truck tags suggest an approachable theme rather than a technical vehicle simulator.
