What is rosettaball.com?
Rosettaball.com is a playable simulation for Rosetta Ball, a UK-patented* electronic puzzle toy.

The Rosetta Ball toy is a sphere with ten shapes on its surface. During play, shapes pop up, and the player can press them back in.

When shapes are popped out, most of them can be rotated into different positions.

A processor controls rules, which determine which shapes pop up for any given action.

The rules can vary from puzzle to puzzle, which means there are limitless puzzles & solutions.

*[UK patent no.: GB2473192]
How do you solve puzzles?
At the beginning of each puzzle, a certain number of shapes will pop out from the Rosetta Ball.

The objective is to return all the shapes to their 'home' position: pressed in, and with the red or blue marker dot pointing towards the same colour circle.

Each puzzle has a set of rules that determine what actions cause which shapes to pop up, as well as what the player can do to prevent them.

To solve a puzzle, the player must work out what actions cause which shapes to pop up, and what can be done to overcome this.
What actions cause shapes to pop up?
One or more shapes can pop up when a player either presses another shape in, or rotates a shape.
What can I do to prevent shapes popping up?
This is the key to solving Rosetta Ball puzzles. Once a player has worked out what actions cause which shapes to pop up, they must find the methods of preventing this happening, so all the shapes can be pressed back in.

There are various ways that shape pop-up rules can be overcome:

Order Of Press
For easy rules it can be as simple as the order in which shapes are pressed.

Example: if pressing the Blue Circle makes the Red Circle pop up, then the solution is to press the Red Circle in before pressing the Blue Circle.

Shape Position
The current position of other shapes can be the solution.

Example: pressing either circle makes the other one pop up, unless the Blue Bar is turned to its second position. In this case, the puzzle is solved by rotating the Blue Bar, then pressing both circles in, before rotating the Blue Bar back and pressing it in.

Shape Status
In some puzzles, the current state of another shape (whether it is pressed in or popped up) might be a factor.

Example: pressing either circle makes the other one pop up, unless the Blue Bar is turned to its second position and pressed in. In this case, the puzzle is solved by rotating the Blue Bar then pressing it in, then pressing both circles in, before finally rotating the Blue Bar back and pressing it in.

Actions
In some cases a preceding action might be required, such as pressing or rotating another shape. Note this is different from shape positions or states, in that as long as the action has been performed, the resulting position or state may not be important.

Action Sequences
In more complex puzzles, a series of consecutive presses and/or rotations may be required to unlock the rule.

In very difficult puzzles, it may be the case that an Action or Action Sequence has to be performed immediately prior to the critical rule action, rather than at any time during the puzzle solution.
Are the rules different for every puzzle?
Yes and no. No two puzzles have an identical set of rules. However, rules do not change for puzzles within the same Level.

The start positions (which shapes pop up and the beginning of the puzzle) may change, and extra rules can be added, but if you work out a rule for the first puzzle it will remain valid for the rest of the level.

Within each level, puzzles will get progressively harder. Try to remember rules that you have figured out as you go.

When you move to a new level, the rules start over and can be completely different.
How do I work out what rules apply to a puzzle?
Rosetta Ball is a logic puzzle. You need to use trial & error, deduction, process of elimination and intuition to unlock the solution!

Remember that rules within a level remain the same from one puzzle to the next.

If you get stuck, use the ‘Hint’ button to reveal rules. Use this sparingly though, as you have a limited number of hints.
How does the leaderboard ranking work?
Puzzle solutions are ranked as a factor of the solve time and the number of moves taken. Fewer moves and faster completion will move you up the leaderboard for any puzzle.

You can toggle the board to see a list of the fastest solutions, and fewest moves, separately.
What is the Memory Game?
The Memory Game is a simple game that helps you get familiar with the shapes on Rosetta Ball, and the way they move.

At the start of the game, all the shapes will pop up. Then one random shape will either turn or press in. You need to remember which shape moved and how.

The Rosetta Ball will then reset, and you need to make the same action on the same shape.

If you make the action correctly, you'll then be shown another random action. You now need to repeat both actions in sequence, one after the other.

If you get both right, you'll be shown a third action, and so on.

Try to repeat as many actions you can to record the longest sequence...
