How to play Gem Grab
Gem Grab is a realtime chase on an 18×12 arena. One gem appears at a time, and both players race to touch it first. Rounds are short and fast, so it is a good pick for a quick break.
Rules
Each player keeps moving in their current direction. Reach the gem and you score a point, and a new gem appears somewhere else on the board. The walls stop you rather than wrapping around, and the two runners pass through each other, so it is all about choosing the shortest route. The first player to collect 8 gems wins.
Controls
Steer with the arrow keys or WASD, or the on-screen direction buttons on touch screens. You keep moving until you change direction.
Tips
Move towards the centre after each pick-up so you are close to wherever the next gem appears. Turning early is better than overshooting, because you keep moving until you change direction.
