Neural Grid is a fast, endless logic puzzle where you drag paths through connected number blocks so their values add up to a target sum. Every clear collapses the board and pushes new rows up from the bottom — so the longer you think, the higher the risk. Chain smart combos, save bombs for emergencies, and see how long you can survive the rising grid. Free to play in any browser, no download required.
Skills Neural Grid trains
Neural Grid is built so that problem solving is the thing that gives out first, which is what turns a round into practice rather than just play.
Problem solving
Problem solving is the ability to look at a situation you have not seen before, break it into smaller parts, and find an order of steps that reaches the goal.
More games for problem solving →Decision power
Decision power is how quickly and how well you choose between options when you cannot have all of them — picking the move that is good enough, right now, instead of freezing on the perfect one.
More games for decision power →Focus & attention
Focus is the ability to keep your attention on one task and ignore everything else for a stretch of minutes, and to notice the moment your attention slips away.

How to play Neural Grid
To play Neural Grid, drag a path through connected number blocks so their values add up exactly to the target sum shown above the grid.
- 1Read the target. Check the target sum shown above the grid before you move.
- 2Drag a path. Click or tap a block, then drag through connected neighbours to build a chain.
- 3Hit the sum. Release when the highlighted chain's numbers add up exactly to the target to clear them.
- 4Beat the rise. Clear chains quickly — new rows keep pushing up, and the board ends if it overflows.
- 5Use bombs. Spend a bomb to detonate a tricky cluster when you're running out of room.
