Opening an account with this game takes one press: Open the holding, above, and it loads on this page itself — nothing downloads and no form stands between you and the first decision. It is drawn for a landscape (wide) screen and takes its instructions from mouse, keyboard or touch, as the game prefers. The file is drawn wide, for a landscape screen — turn a phone sideways, or let a tablet or desktop give it room to breathe. If a fullscreen control is offered, take it — a growing enterprise deserves the whole desk.

Analyst's notes for strategy holdings

• Write the plan before the first move, even if the plan is one sentence. Strategy games punish improvisation politely and reward a rough intention revised on purpose.
• Spend your first session on reconnaissance. Watch what the game charges you for — time, space, resources, attention — because that price list is the whole game in miniature.
• Keep a reserve uncommitted. The player who deploys everything into the opening has read only the first page of the problem; the answer usually arrives in chapter two.
