Falling blocks, lightning, exploding bombs, tiny buddies to rescue, and a banging arcade soundtrack. What could possibly go wrong? (Everything. The answer is everything. Also it's great.)

Works on desktop and mobile. Swipe, tap, drop, win. 📱
| Mode | Vibe | What's the deal? |
|---|---|---|
| ⚡ Rush | Two minutes. All or nothing. | Race the clock (1, 2, 5 or 10 min) with power pieces, bombs, buddies and the exclusive Overdrive pulse. Pure chaos, maximum points. |
| 🎯 Sprint 40 | Old-school speedrun. | The 7 classic pieces. Clear 40 lines. As fast as humanly possible. No gimmicks, no excuses. |
| 🍃 Zen | Breathe in. Stack out. | All the power pieces, stars and buddies with no timer breathing down your neck. |
Rush and Zen throw a Surprise Mix at you. Classic blocks, plus some party guests:
| Piece | What it does |
|---|---|
| ⚡ Lightning | Zaps every block in the columns it touches, top to bottom. Vertical hits 1 column, horizontal hits 3. |
| 🌈 Prism | Finds the most common color on the board and makes it vanish. Poof. |
| Slices a diagonal line right across the board. Rotate to pick the angle. | |
| 🚀 Rocket | Launches on landing and clears every block in its path. Rotate to aim down, left, up or right. |
| 💣 Bomb | A 9 × 9 kaboom. Rescues buddies in the blast and sends the leftovers tumbling. |
| 🧩 Mini, Duo, Corner, Horseshoe | Weird little shapes for weird little gaps. |
Every so often, a six-piece streak queues six identical classic pieces, with a glowing queue and a special sound. Hold still works, and buddy gifts wait until the streak finishes.
🐦 Birds fly through empty board space. Hit one with a falling piece, a power, or a click/tap for 300 points × level (doubled in Overdrive).
Empty the whole board and you get an ALL CLEAR... with fireworks. 🎆
Mimi, Lumi and Pip are cheering you on! (Mostly Mimi. Mimi is very supportive.)
Buddies and ⭐ stars pop up on the board. Land a piece on them before they disappear:
- ⭐ Star → 200 points × level
- 🐱 Buddy rescue → 500 points × level
Some buddies bring... side effects. Rescue them and hang on tight:
| Buddy | Special talent |
|---|---|
| 🙃 Nox | Flips your world upside down for 10s |
| 🏎️ Turbo | Turbo drop! Pieces fall faster for 10s |
| 📏 Lino | Only I pieces for 10s (you're welcome) |
| 🔩 Broca | Drill mode: every piece bores straight to the bottom for 10s |
| 6️⃣ Sexto | Lines clear with just 6 blocks for 15s |
- Three missions per game: hit 3 birds (+750 points), rescue 2 buddies (+1,000), and clear lines with 3 consecutive pieces (+1,500). Sprint swaps birds and rescues for clearing 8 lines and placing 20 pieces. Each reward is paid once per game, at its fixed value.
- Buddy album: every rescue is saved on your device. Find all 10 friends, then rescue each one 3 times for an Aurora color, 5 for a crown, and 10 for a heart shower. New looks equip automatically; open the album to choose your favorites. They appear on the board and cheering buddies.
- Beat your best: track the gap to your personal record, get a nudge near the target, and celebrate passing it with a fanfare and fireworks. Records stay separate by mode and board size; Sprint compares completed times.
Open Missions or Buddy Album above the board at any time. The game pauses while you look. The results screen shows completed missions and the next album milestone.
Place pieces and clear lines to charge your pulse. When it's full, smash D and:

No bundler. No npm install. No build step for the game. dist/ is the source.
It's included in .NET builds and publishes as-is.
GitHub Pages publishes the main branch from / (root). The game lives in
dist/index.html, so the URL includes /dist/. The online version serves the
static files directly and doesn't need the ASP.NET Core host.
Static file hosting follows the ASP.NET Core documentation.
Made with ☕, 🧱 and way too many "just one more game" moments.
