Thanks for the feedback. Yes it takes some practice to be able to read and understand an orderbook, and I find that visualisations help a lot, so does making your own derived metrics (for example calculating vwap prices, distance to fair in basis points for each level etc). What this game does is provide a feel for it, for your relative position, and for visualising pockets of liquidity, but it's also quite limited by the form factor.
I drafted another version of this game which is more arcade-based (and does not run on handheld but a computer or arcade box) and the game is essentially about fighting over an orderbook to (a) be in the best position possible to capture the flow that you want, (b) monitoring for orders with a positive edge and sniping them faster than the other player (or even pick off the other player before they have a chance to move). The values next to the bid and ask quantities are the edge in basis points relative to faire value. If you see some positive edge somewhere you want to go and cross the book to pick out the price.
