How to Play Rolling Deep (in a nutshell)

About Rolling Deep, from BoardGameGeek:

Join a trio of daring dice-head adventurers descending into the heart of a restless volcano in search of glory, treasure, and the secrets at the center of the Earth. Each chapter of your journey brings new obstacles, strange tools, and terrifying creatures. Roll, adapt, and push your luck as the depths grow darker … and trust that friendship will prevail! Rolling Deep is a Balatro-inspired roguelike dice-building adventure featuring a cornucopia of unlockable content, addicting challenges, and delicious combos. Each round, you roll dice representing your team's daring actions as you push deeper underground. Decide when to act (scoring a roll) and when to try your luck (rerolling individual dice in pursuit of a stronger outcome). When you score a roll, its value advances your progress toward a target score, the difficulty required to overcome the current stage of the journey. Each set of 3 rounds is called a chapter. Each chapter raises the challenge, and the final round of every chapter features a boss - a dangerous encounter that alters the rules for that round. Between rounds, you visit the shop, where you spend coins to acquire upgrades and consumable gear. Some upgrades permanently alter the sides of your dice, changing their values and allowing them to generate coins or reroll potions when scored. Others boost your score, either every roll or when you score specific result ranges, rewarding careful control over how boldly (or cautiously) you push forward. Your most valuable resources are time and reroll potions. Time determines how many opportunities you have to score your dice and accumulate a total score for the round, while reroll potions allow you to take a chance and - you guessed it - reroll individual dice before committing to a result. Your goal is to survive 5 chapters and reach the volcano's core. If you can overcome the final boss, you claim the treasure of the deep and escape, winning the game (and possibly discovering more mysteries to pursue in another expedition). If you fail to meet a round's target score, you lose. Better luck next expedition! With each run, strive to complete new achievements that unlock hundreds more cards to utilize and challenges to overcome! Rolling Deep is the first title in Bitewing Games' new Table for One Series - a line of solo-only games featuring oodles of challenges with vintage cartoon art. -description from the publisher
