CubeRealm io

CubeRealm io combines creativity through Block-building with the excitement of a shared online environment that includes Mining, crafting, building, and Survival. In this world, you will have open access to new environments, be able to collect useful items and modify the landscape as you see fit, and have complete control over how much time you want to devote to developing your peaceful home versus how much time you want to devote to competing against other players in multiplayer. Although very simple to learn, the amount of freedom you have within this world allows each player to develop his/her own unique journey.

Game overview

CubeRealm io is an online multiplayer sandbox adventure game that provides the ability for players to enter a world made up of voxels (blocks) and create their own objectives. Players can dig blocks out of the ground, collect resources, create better digging tools, build homes/shelters, discover new regions of the world, and communicate with other players in common areas. The flexibility of the game means that one player could be busy creating his/her dream home while at the same time another player would be searching below the ground for better quality resources.

This type of game succeeds due to the fact that it creates lasting value for players from seemingly simple actions. Digging is not merely a way to break blocks, but rather is a method of obtaining more powerful digging tools and/or reaching further away locations. Building is not only about decorating the world, but rather can provide players with protection, organization for their belongings, and character/personality to their world. Exploration is important because different levels of the world and different areas of the world may contain additional resources and challenges.

In addition to being flexible enough to support multiple types of play, CubeRealm io has been designed to accommodate different types of players. For example, players who prefer peaceable activities such as building and discovery can do so, while players who prefer Survival-type activity such as gathering resources, protecting themselves and their efforts, preparing for potential dangers, etc., can pursue these interests. Additionally, the "creative" form of play offers players yet another option to utilize when they wish to engage in building activities without having to worry about Survival pressures.

Features

  • A multiplayer online sandbox world with Mining, crafting and exploration.
  • Block based building for homes/bases/custom structures.
  • Play styles for Survival and creative.
  • Progresion of resources: wood -> stone -> ore -> higher level resources.
  • Shared online worlds in which players can co-op/build/compete.
  • Browser friendly controls for ease-of-use/accessibility for long gaming sessions.

Tips for new players

  • Gather basic materials before venturing too deep.
  • Craft simple tools early to make Mining and building easier.
  • Build a small home/base to help you organize your items and protect your progress.
  • Practice using the inventory controls before traveling to high-risk zones.
  • Be cautious when using chat and commands when in a shared world.

Advanced Tips

  • Before building your base, consider planning out your base's layout instead of building in a random manner.
  • Venture into underground areas if you require stronger ore and upgraded tools.
  • When possible use safe or protected zones to minimize loss of work when damaged.
  • Have some spare tools handy prior to lengthy Mining excursions.
  • While in creative mode use flight and un-restricted building to construct large-scale designs quickly.

Common mistakes

  • Not planning out your Mining strategy may result in you being far removed from useful resources or safety.
  • Not managing food/tools/protection properly may add to the difficulty of surviving.
  • Constructing your base in an exposed area may allow others to easily locate/find/damage your base.
  • Spending high-quality resource material too soon may limit your future resource development speed.
  • Believing Survival mode is essentially the same as creative mode may cause frustration/confusion.

If not available, you may need either permission or a server that supports it.

  4. Is CubeRealm.io like Minecraft?

Final thoughts

CubeRealm io offers players a great opportunity to engage in open ended games that bring together both creative and Survival elements. As the controls are relatively easy to master, there are numerous reasons why you will continue to want to play (better tools/new resources/deeper areas/safer homes/larger ideas). Depending on how much time you dedicate to creative pursuits (building), and how much time you dedicate to Survival/pvp (multiplayer interactions), you may experience extreme calmness when building a structure and/or extreme intensity when focused on Survival/pvping.

For players interested in a browser-based sandbox game that incorporates crafting/building/exploring without requiring extensive preparation/registration/set-up on Rocket Games, CubeRealm io should be a viable alternative. Regardless of whether you desire to mine underground or build above-ground, test creative ideas or simply navigate a shared world, CubeRealm io presents you with an accessible platform to begin.
