More about this game
Your goal is to fit all provided neon blocks onto the grid so that every row and column matches the required glowing edge counts perfectly. The core loop involves dragging blocks into open slots while avoiding dark forbidden cells and working around pre-placed fixed blocks. Difficulty scales across 11 distinct stages as grids introduce more complex piece combinations like the T4 and O4 blocks. A run ends when you clear all 11 stages, which loops the protocol back to the beginning.
Tips
- You have 75 seconds on the timer, but you can still finish for base gold if it runs out. Every four seconds remaining adds extra gold.
- Double-tap a block while dragging to quickly rotate it without dropping it, or use the ROT button at the bottom of the screen.
- Save up your gold to unlock new neon skins in the shop. The Cyan skin costs 80 gold, Pink is 140, and Gold is 220.
Questions
What happens if the 75-second timer runs out?
If the timer depletes, you can still complete the puzzle. You will simply earn the base gold reward for the stage difficulty without the extra time bonus, allowing you to finish at your own pace.
What are the dark cells on the grid?
The dark cells with crossed lines are forbidden areas. You cannot place any part of a block over them. You must rotate and position your pieces to fit into the remaining open spaces.
How is the gold reward calculated?
You get a base amount based on the difficulty, plus three gold per stage level, and one extra gold for every four seconds left on the timer. You can also double this reward after winning.
