Progress to 100 manages to bypass this hurdle totally namely because this is a game based around the total concept of telling the player actually what to do. Your job, as the instruction suggests, is to touch the screen just where the game tells you to by placing your digit on top of the word ‘here’ until the total display changes color, filling in from left to right.

Surely, the developer Ludosity would appear to have set out to make use of every contact point, every form of interaction that you can fashion with an iOS device. Progress to 100 is either a game you play on your own or one you play in a group, where communication and co-operation help unlock the puzzle. Progress to 100 is a game designed to make you think out of the box and take risks, which is where, as an experience, the game potentially runs into trouble.

With no reward on offer other than your own satisfaction that you cracked the code and the unlocking of the next stage, joy is peculiarly short lived. Before you have had a chance to digest the dispute you have overcome, you are taking already on its successor.

Finally, Progress to 100 feels like the kind of game that sounds great on the drawing board and was no doubt bags of fun for the developer to work on, but it is missing a vital factor to create it anything other than a well made novelty. Once the novelty of the first ten levels has worn off, Progress to 100’s appeal starts to wane, particularly if you are playing it alone.

The biggest hurdle in your path, in fact, is getting over a fear of failure. Instead of sitting twiddling your thumbs, scratching your head, waiting to stumble across a solution, your best tactic is exactly to experiment.

Progress to 100 is a puzzler at core, challenging you with performing simple touch or accelero-meter based tasks.
