Once you reach that score, the game essentially becomes an endless runner, with no further changes in gameplay. After 99999 score, the dino game resets your score back to 0 but the speed is set to 6000. And, this happens every time you reach 99999 score.

After their enemies' destruction, the Rangers go their separate ways as Koda and Ivan finally go back to their own times, Heckyl becomes the guardian of the Dark Energem as he and Zenowing return to Sentai 6, and Keeper returns to his home planet.
