Bus Blast - a complete bus parking puzzle game for Android

Bus Blast is a ready-to-publish bus jam / parking puzzle written in Kotlin with Jetpack Compose. Players tap a bus whose road is free; it drives to the parking and the passengers of its colour run and jump on. It targets API 36, ships with 1000 levels, 3 boosters, AdMob with Google consent and Google Play Billing. Open it in Android Studio, change the name, IDs and artwork, and publish.

Tap, park and board

Buses stand straight and tilted in a real jam. A blocked bus rolls forward, bumps and honks. Hundreds of passengers wait on two roads in one-colour groups, and nobody knows which colour comes next.

VIP, Arrange and Jumble

• VIP: send any bus to the gold VIP spot, even a blocked one; its colour jumps in from anywhere in the line
• Arrange: brings the right passengers to the front
• Jumble: shuffles the colours of the buses on the board

1000 levels, harder every time

Bigger boards, more colours and longer crowds. "?" buses show their colour only when their road is free, and garages send out the next bus with a surprise colour. Every level is checked to be solvable by an automated test.

Players come back every day

7-day daily rewards, a free lucky spin, three daily missions, coins for every win, bus styles to unlock and a 3D toy train between levels.

Monetization built in

AdMob banner, interstitial (every 2 levels) and rewarded ads with the Google User Messaging Platform consent flow. Rewarded videos unlock parking spots and give free boosters. Play Billing 9.1 for coin packs and Remove Ads.

Easy to reskin

Backgrounds, logo, buttons and 3D sprites are plain image files; every gameplay number is in one GameConfig object.
