Bim! is an open-source online multiplayer game where up to four players share a small arena and try to be the last one alive. Julien Jorge develops it, and the code is released under the AGPL-3.0-only licence. The game costs nothing, shows no ads, and runs on Android 6.0 or newer.
Four players, one arena, bombs only
The whole game rests on one idea: last man standing. Each match puts up to four players in a small arena with crates scattered around it. You drop bombs to break the crates, and in the end you use them against another player.
Bim! is listed under offline games on TopDown APK, but it is an online multiplayer title. Expect to need a connection for matches.
What a match looks like from start to finish
A round starts with crates to clear. Some broken crates reveal bonuses such as extra bombs or a longer blast distance, so early play is partly about collecting and partly about staying out of reach.
As you progress, the game unlocks extra gameplay features. You pick the ones you like, and they combine with the choices of your opponents. Every feature affects all players in the match equally, which is how the developer describes the lack of pay to win. The game is free and shows no ads.
Bim! next to Mindustry and Wesnoth
The listed alternatives are Block Blast!, Mindustry, The Battle for Wesnoth, Candy Crush Saga, Subway Surfers and Offline Games: No WiFi. Mindustry and The Battle for Wesnoth are the closest in spirit, since both are known as open-source titles, though neither is a short arena brawl. Block Blast!, Candy Crush Saga and Subway Surfers are casual games of a different kind.
What sets Bim! apart in this group is the head-to-head format with up to four players. The package is 62 MB, with 8 screenshots on the listing.
