several consecutive clicks. This behavior is also seen in the distributions of jump lengths, since they show a large deviation from the exponential for one-cell length jumps, which are overrepresented in the dataset (Figure \[fig:blindexp\]a). The higher frequency of turning angles closer to zero is linked to the higher presence of jumps of length one. The explanation for this persistence in the direction of movement shown in Fig. \[fig:blindexp\]b,c is probably a combination between the attempt of some players to design purely systematic strategies and the intrinsic tendency of humans to keep visually scanning in the same direction [@amor2016persistence].

As an exception, movements done immediately after a yellow-to-black transition show a strong tendency to reverse the direction, as this sequence in the colors of the cells indicates that the player is moving away from the target (Fig. \[fig:blindexp\]d).

Experiments with initial information and square neighborhoods. The case of $N_{\mbox{\tiny{y}}}=5$ as compared to the blind case {#sub:know .unnumbered}
--------------------------------------------------------------------------------------------------------------------------------

In this second series of experiments the players know the size of the yellow region, which is fixed at the optimal interaction range $N_{\mbox{\tiny{y}}}=5$. This increases the quality of the information obtained when one of the yellow cells is found as the
