    Patch 1.2 - The Stars Align

    Hey everyone. Patch 1.2 just dropped and it's a big one. I've been heads-down on this for a while, so let me walk you through what's new.New campaign chapter: Stars AlignFour story missions and four puzzles. All set in orbit with a new cosmos board and a starfield look.New PRO difficultyI built a new AI tier that actually plans ahead. No more fixed rule trees. PRO opponents use deep lookahead, they read several moves out, and they will punish you for sloppy plays. RONALD DUMP is backI brought him back as a boss table on his own difficulty slot. Beat him and you'll re-enable a long-dormant achievement that some of you have been asking about for a while.Full visual overhaulMain menu, in-game HUD, shop, campaign screen, notifications, tutorial, ending screen. All rebuilt. New art, new lighting, way more polish across the board. The game just looks and feels different now.Difficulty select screenBefore you jump into a Quick Game, you now pick your opponent: Easy, Medium, Advanced, Pro, or Ronald Dump.Bigger XP rewardsTougher opponents now pay out way more XP, up to x2.5. Grinding against Easy for pennies is no longer the move.Achievement fixesDividentalist and Win Streak (5 and 10) now actually track and unlock properly. If you were stuck on those, give them another shot.See you on the board.PS: I've also been working on Oil Sheik: Dominion a turn based 4x game if you're more about tanks and shooting aliens.

    Oil Sheik Patch 1.1 - China In Your Hands

    Patch 1.1.0 is LIVE!What's up Sheikhs,This is a massive update. I have been working hard under the hood to bring you a networking system, smarter AI, and entirely new strategic mechanics. This is the first step moving away from a pure solo experience.Here is what’s new in Oil Sheik 1.1: China In Your Hands.🐉 New Mission: China In Your HandsAn incredibly hard challenge awaits in the campaign mode.Unlock Requirement: Earn 15 Stars in previous missions (or puzzles) to unlock.The Reward: Completing this mission awards the exclusive "Dragon's Breath" Card Back, with a cool particle spirit that orbits your card and dives onto the board when played!New Mechanic: Spin-OffsIs a company getting too big to control? Use the new Spin-Off mechanic to shake up the board (available in Quick Game/Custom Rules).How it works: If you are the Majority Shareholder of a massive company (15+ tiles), you can force it to split.The Result: A chunk of the company breaks away to form a new entity. Shareholders receive mirrored shares in the new company, but the "bridge" tiles connecting them are destroyed, lowering the parent company's value. Use this to generate capital or sabotage a rival's net worth!Multiplayer BetaYou can now host and join games directly via Steam and play against your friends.Steam Lobby Integration: Create Public, Friends-Only, or Private lobbies.Bot Support: Fill empty slots with AI opponents of varying difficulty in online matches.Note: This feature is experimental. I have written the synchronization logic from scratch to ensure smooth gameplay, but please report any issues you find!Smarter "Pro" AIThe Advanced AI has gone to business school and learned some new things:Relative Wealth Calculation: The AI no longer just looks at its own profit. If a move makes you richer than it makes them, they will act smarter.Defensive Blocking: The AI will now more actively block mergers or expansions if it knows you are about to cash out a massive majority bonus.Visual & QoL Improve...

    Weekend Hotfix & Oil Sheik v1.0 Now Live

    This update includes a quality-of-life improvement and a bug fix based on recent player feedback. The mission selection screen now automatically highlights the next available sub-mission. Previously, it always defaulted to the main chapter overview, which could make it seem as if progress wasn't being saved. The 'End Turn' button is now correctly highlighted when it becomes the only valid action for a player (for example, after placing a tile when no stocks are available to purchase). Thank you for your feedback! Please continue to report any bugs or share your thoughts so they can be addressed. Email: oilsheikgame@gmail.com Discord: https://discord.gg/zQC4H3RbZ7

    Missions & Puzzles Update is LIVE! + Important Info

    {STEAM_CLAN_IMAGE}/44852842/1c528e28637619c029c91aa5b3ad3dc93f912ef6.png Hello everyone! I'm thrilled to announce that a major update has just gone live, adding a core pillar of brand-new content to the game: Puzzles and Missions! Puzzles Inspired by chess puzzles, these offer a fresh challenge compared to standard AI matches. Puzzles feature: Pre-set starting conditions on the board. Specific objectives to achieve within a limited number of turns. A focus on finding optimal strategies and solutions – efficiency is key! Missions Missions are similar in structure to Puzzles but emphasize thematic scenarios and often involve competing against AI opponents of varying difficulty levels to meet specific goals. Star Rating System Both Missions and Puzzles use a 0-to-3 star reward system: 0 Stars: Objective failed. 1 Star: Objective met (generally achievable). 2-3 Stars: Awarded for exceeding the basic objective, often requiring more optimized play and presenting a significant challenge depending on the specific mission or puzzle. These additions aim to bring more variety, replayability, and engaging challenges to the game! What's Next? Over the next two months, I'll be dedicated to further improving these new modes, adding a significant amount of new Puzzle and Mission content, and diligently fixing any bugs that arise. The road to the full Q3 release is busy, but exciting! Feedback & Community (Readme) Your feedback is invaluable! If you encounter bugs, have suggestions, or want to discuss the game, please join the official Discord server: https://discord.gg/zQC4H3RbZ7 Your input helps shape the game and make it the best it can be for the full release. Important Note on Pricing & Early Access Now is a great time to add the game to your library if you haven't already! The game is currently free during this development phase. With the planned full release in Q3, the game will transition to a paid title with a small price tag. However, anyone who has the game in their Steam...
