Some good games to play on SmartBoard.com include "Monster Must Die" and "Pour the Fish." As of 2015, both of these games are available to play online for free.
"Monster Must Die" is a game where players must determine the angle to shoot their player in order to collect all the goodies and kill the monster. Players can move forward one round without winning but must win that round to keep advancing. This game offers many levels, each getting progressively more difficult.
In "Pour the Fish," players must create a path to get enough water to the fish to hydrate it. This involves creating paths at the correct angles for the water to continue to flow to the fish.
