A board of wells. Balls keep dropping in. Line up five of one colour before the board fills up. Matrix Balls is the classic colour-lines puzzle, played against a machine that never stops. Drag a ball along the empty wells to any spot it can reach — across, down or round a corner — and line up balls of one colour in any direction, including the diagonals. Complete a line and it clears, with points for every ball in it. A CLOCK THAT DROPS BALLS Every twenty seconds the machine drops a handful of new balls onto the board. Every move you make resets the clock, so keep moving. A move that clears nothing brings the next drop straight away. Sometimes the machine completes a line by accident. You still get the points. IT GETS HARDER Your score carries you through nine stages. Each one brings more colours into play — seven at the start, eleven by the end — and bigger drops. The line you need is four balls on a small board, five on a large one. Fill the board and the game is over. Your best score stays. A BOARD THAT FITS YOUR SCREEN The grid is laid out for the display you are on: a tall narrow board on a phone, a wide one on an iPad or a Mac window. Bigger boards mean bigger drops and longer lines — it evens out. ONE GAME, EVERYWHERE iPhone, iPad and Mac, with your best score carried between them over iCloud. Compare it with other players on Game Center, or ignore the leaderboard entirely. Leave a game mid-way and it is waiting when you come back. NO CATCHES No ads. No in-app purchases. No account to create. Nothing to subscribe to. It works offline — there is no server behind it. Light and dark, and it respects Reduce Motion.

Verdict
The clearest difference is in-app purchases: Matrix Balls at none against ilu's 9. Matrix Balls also leads on review sentiment (100% vs 69%) and update cadence (every 4 days vs every 3 weeks). ilu's advantage is ratings volume (2.1K vs 4) and iOS requirement (9.0 vs 17.0). On ads, monetization model and device support there is nothing between them.
