Pebble Math v0.5

Controls

Double mouse click or press space or drag and double tap on mobile. Mobile runs full screen and black areas can be dragged to give you more positions to throw from.

Rules

Three stones will be thrown towards the centre of the board or dropped from above

The players can throw stones in the area they think is best to throw

Throws are randomised

Landing on a Line gives a 1 ( | ) and Black spaces give a 0 (■)

Landing where two or more Lines meet (a cross section) means you get to add values together (+) and landing on a White space means you get to invert one add operator into a minus operator (□)

This means you can minus instead of adding to lower your score

Ones can be split to get lower numbers (10 and 10 can be 100 and 1)

You must use up all the 1s you have

Normal maths applies, so 1+1-10 = -8

0s must come after 1s

1s can follow 1s

Stones can become out of bounds by falling off. Any fallen stones will add +20 to the score

The goal is to get the lowest score you can

You have 3 throws with 3 stones which means you get to make a sum with 9 pieces

3 stones and 3 throws is one round

If you have no 1s then your score is one 0 minus the left over pieces (equal to -20 each which is -160 max) not including any stones that have fallen off
