Sliyalki is a merge game that features 2048, Hexa and Suika elements. The player evolves numbered hexagon shapes by merging identical pairs for as long as possible. They also attempt to earn a high score and claim a specific number of star coins.
This game features a mounted circular wire frame container. As a result, any time the player drops a hexa into the container, the shape slides along the curved sides and come to rest near the bottom center. Each shape also bounces like a ball during a drop or merge. To prevent mistakes, the player must take these factors into account when considering drop strategies.
Sliyalki displays the main drop hexa above a horizontal line and a slightly shaded secondary preview hexa above it. The player can use this information to make more successful merges.
That said, the game also makes play more difficult over time by removing the preview shape entirely. It randomly transfers a container shape sometimes to a position behind or in front of the current drop shape, which makes the color and number of the next shape hard to determine for planning precise merges. Additionally, it randomly auto-swaps the hidden and front shape before the next drop.
To prevent shape pile-ups caused by these tricks, the player claims coins with ad views and then buys access to boosters below the container. The first booster removes all instances of the lowest-numbered hexa from the container. The second booster removes all instances of the next-highest numbered hexa.
