Jelly Reactor

Place colourful blocks on an 8×8 board and complete rows or columns. Clear same-colour cells to earn special blocks, then activate them with another line clear. Chain different powers to trigger Overload and chase your best score.

How to play

Drag a block from the tray onto the board. Alternatively, select a block, click a valid position to preview it, then click that position again to place it.

Free experimental browser release. Best played on a desktop browser with a mouse. Feedback is welcome in the comments.
