What MossBastion Is & How Our Facts Strips Work

MossBastion is an independent informational guide written for players aged 16 and over. We do not host playable games on our servers, create player accounts, or process payments. Instead, we review nine free-to-play browser strategy games based on official publisher documentation (last checked on ) and provide direct links to each game’s official website.

Along the High Watch-Parapet, Chief Siege-Architect Bryona Vane pairs every game review with a standardised facts strip. Before anyone follows an external link to play, you can check that facts strip at a glance to see:

  • Price & In-Game Purchases: Whether the game is free to play with optional in-game purchases, and whether those purchases include paid random items.
  • Advertisements: Whether the browser version displays third-party ads or optional reward videos.
  • Account Requirement: Whether a player must register an account with the publisher to save their settlement.
  • Multiplayer Chat: Whether the game includes live text chat, guild forums, or direct messaging with other players.

Understanding Browser Strategy Games

Four Key Areas for Households

Strategy games revolve around long-term planning, resource management, and diplomacy. Here is how their commercial and social systems operate in plain terms.

In-Game Purchases & Paid Random Items (Loot Boxes)

All nine games featured on MossBastion are free to play in a web browser, meaning no purchase is required to start building a city or stronghold. However, they offer optional in-game purchases bought with real money.

In strategy games, optional purchases typically buy premium currency (such as gems, diamonds, rubies, or gold), starter packs, VIP subscriptions, or speed-up items that shorten construction and research timers. Because buildings and technologies often take hours or days of real time to complete, players may feel tempted to spend money to skip waiting.

Some games also include paid random items—often called loot boxes, mystery chests, or hero summons (gacha). When a player buys or opens one of these using paid currency, they do not know the exact item, hero, or reward they will receive beforehand; the outcome is chosen by chance. We note in each game’s facts strip when paid random items are present.

Switching On Device & Store Spending Controls

Phones, tablets, computers, consoles, and digital app stores all include built-in spending controls that parents and carers can switch on to prevent unexpected charges or require a password before any purchase is made:

  • Web Browsers & Payment Methods: Do not allow the browser to auto-save credit card, debit card, or PayPal passwords. Enable two-factor authentication or PIN verification on your payment accounts.
  • Apple (iOS / iPadOS / Mac): Use Screen Time and Family Sharing settings to turn on Ask to Buy or block in-app purchases completely under Content & Privacy Restrictions.
  • Google Play (Android): Open Google Play settings to require biometric or password authentication for every purchase, and set a monthly budget or family approval rules via Google Family Link.
  • Windows, Xbox & PlayStation: Use Microsoft Family Safety or PlayStation Family Management to set spending limits and require parent approval for store transactions.

Checking Age Ratings at PEGI.info

In the United Kingdom and across Europe, video games are classified using the PEGI (Pan European Game Information) system. A PEGI age rating (such as PEGI 7, PEGI 12, PEGI 16, or PEGI 18) indicates whether a game’s content is suitable for a particular age group—it does not measure how difficult the game is to play.

Alongside the age label, PEGI provides content descriptors that flag specific features such as Violence, In-Game Purchases (including whether a game contains Paid Random Items), and online interaction.

Note that some older browser-only games may not hold a formal PEGI certificate on their web portal, or their rating may be registered under their companion mobile app. You can search for any game’s official age rating and content descriptors at the official PEGI database:

Alliance Chat & Independent Publisher Rules

Stronghold strategy games are persistent multiplayer worlds. Players routinely join guilds, tribes, or alliances where they can communicate with other players—including adults—through live text chat, alliance message boards, and direct mail. Encourage young players never to share their real name, school, location, phone number, or passwords in game chat, and never to move conversations onto external messaging apps.

When you click a Visit Official Site button on MossBastion, you leave our website and go directly to the third-party game publisher’s site. Each game has its own privacy policy, terms of service, and minimum age rules.

Under UK and European data protection rules, publishers often require players to be at least 16 years old (or to have verifiable parental consent) to register an account. Always check the publisher’s terms and privacy notice on their registration page before creating an account.
