Score to beat: 1,600
On trail #21 the board holds square blocks of four rocks, 32 rocks in total and 8 clumps. The pattern is the same in all four quarters; 14 rows of the board are untouched and 400 cells stay open.
This is a No walls trail: leave the board on one side and you come back on the other, so the border is a shortcut rather than a danger. The snake starts at 10 cells per second and reaches about 10.9 by the 10th fruit.
Test run
In our test run, a simple path-finding player cleared this trail in 14 seconds, scoring 1,600 points. It plays safe rather than fast, so a confident human can beat that time.
How to approach it
The square blocks leave wide corridors between them. Treat each block like a roundabout: circle it on the outside lane and keep the inside clear for the tail.
