Coral Islands is a 2-in-1 game featuring 2 competitive games utilizing dice stacking as the prominent mechanic. Players are tasked with conservation efforts to repopulate coral as well as redevelop islands to make them favorable to animal life.

"Coral," designed by Richard Maass, has players repopulate a shared coral reef using colorful translucent dice. Players take turns stacking dice on the board aiming to score points by finishing structure cards that involve both their own dice and opponents' dice. In addition, players gain tokens representing the fish that live in the reef, which allow them to manipulate their dice or even place two dice on the same turn, generating engaging tactical and strategic tradeoffs between pursuing low-scoring easy-to-complete structure or high-scoring complex structures more likely to get blocked by an opponent, and also between earning points now or focusing on fish tokens to gain flexibility later. Inspiring players to think in 3 dimensions, Coral creates a gameplay experience that feels fresh and unique. The person who earns the most points by completing structures before placing all 16 of their dice (12 in a 4-player game) is the winner!

"Islands," designed by Rohan Dargad, asks players to move around archipelago islands from sea-level in height to mountainous terrain in a concerted effort to reclaim lost land caused by rising sea levels. Players take the roles of conservation charities. The different colored dice represent the different geology of the islands. Every round 3 land cards are dealt which gives the active player the opportunity to move around an archipelago segment. These segments are overseen by conservation specialists which are asymmetric rule changes when a stack of cards is taken. Players will then take and keep one of the cards from the stack to indicate their geological specialism - and move one of the dice on the archipelago a number of times based on the height of the stack of cards. Dice are continually moved around this way , until the end of the game where players with the highest specialisms claim the most mountainous lands to score prestige points. The player with the most prestige wins!
