Boom Chain
Tap-to-place bombs that chain-react across colored tiles; clear the board in as few taps as possible.
Each tap drops a bomb that explodes in a cross pattern, igniting adjacent primed tiles; clear all primed tiles with the tap budget.
Tap any tile to drop a bomb; that's it.
Bomb-pushing logic remixed as a tap-to-chain puzzle with the kaboom kaboom aesthetic.
So-Kaboom proves bomb-puzzle hooks are resonating on itch this week; a one-thumb tap version is a faster mobile on-ramp.
The cited 'trend' is a GMTK 2026 game-jam entry with only 3 ratings published hours ago, and So-Kaboom is actually a Sokoban-style bomb-PUSHING puzzler — mechanically different from tap-to-place chain bombs, so it does not validate a hot hook.So-Kaboom: 5.0 from 3 ratings, released 6 hours ago, bomb-pushing Sokoban variant, not a chain-tap game. ↗
Single-player tap puzzle with no social/multiplayer hook and no obvious fail-clip moment; bomb chain clears don't share well vs. physics-fail or skill-shot games.Existing 'Chain Reaction – Bombs Connect' apps lean on 2-8 player social play, suggesting chain-reaction concepts gain traction via multiplayer, not solo tap loops. ↗
One input (tap) plus a standard cross explosion is trivial to prototype; no asset complexity beyond colored tiles and a bomb sprite.Existing 'Chain Reaction Game' clones are built as simple Android puzzles, confirming the mechanic is easy to ship. ↗
Hypercasual puzzle monetizes via interstitials between boards and rewarded revive/undo, but the category is crowded and ARPDAU on tap-puzzlers is typically modest.Puzzle subgenre on App Store is one of the most competitive; entry requires strong UA spend to break even on ads. ↗
Saturated: multiple 'Chain Reaction' apps already live on Play/App Store and bomb-puzzle is a well-trodden theme, leaving narrow whitespace for a new tap-chain variant.Chain Reaction – Bombs Connect already shipped on iOS App Store, indicating the niche is occupied. ↗
