About

Solitaire Calculation SK

Features
Read full description

*** UPDATE: All themes are free and unlocked now! *** This solitaire "Calculation" is very mysterious compared to the other solitaire games. Because all the combinations are solvable. The first time I met "Calculation" was over 30 years ago. Since then I have been playing and making this game as an app on various computers. About 7 years ago, I suddenly realized that I could solve all the combinations no matter how difficult it seemed. For easy ones, it takes only a few minutes. For hard ones, it may take hours, but in the end it can be solved. You just need to memorize it and think really hard. Sometimes make strategy. Just like chess.

About

Dungeon Guide

Features
Read full description

You are the Dungeon’s Guide. Your mission is to lead adventurers safely through the labyrinth. Every move is a test of your logic, and every decision can change the fate of those who enter. The dungeon is a roguelike sliding puzzle, where each move can change everything. By moving panels, you can alter the paths of adventurers and enemies alike. Navigate carefully to avoid traps and attacks while aiming for the goal. Your strategy and clever thinking will be the keys to success. If an adventurer’s HP drops to zero, it’s game over. Don’t forget to heal with potions or restock at the shop! With enough gold, you can even hire bodyguards-loyal allies who fend off enemies for you.
