Zoo Yatzy

In this Yahtzee-like dice game; players get to throw the five dice up to three times on their turn while attempting to make high-scoring sets; whether of animals; flags; or something else; many versions of this game have been released; and the symbols matter only for what you check off; not for a point value since each symbol is worth 1. Choose carefully which lines to score as each line can be scored only once! If all the possible choices for a roll have been filled; then you must score zero points on another line of your choice.
If you score 18 or more points on the upper half of the score sheet; then you receive 10 bonus points. (Note that unlike Yahtzee; each symbol is worth only one point; note also that in the lower section; each line has a specific scoring combination; e.g. three elephants score only with two bears; not with a two of something else. Roll five identical items; and you get a 10-point bonus. Whoever has the highest score when all the score sheets are filled wins
