SPATIAL PUZZLE / TETRIS-LIKE BOARD GAME (2020) by MICHAL MIKEŠ / JAN SOUKAL / ADAM ŠPANĚL (BOARDCUBATOR, CZECH REPUBLIC) — players fill polyomino puzzle cards with colorful plastic tetromino-like pieces. Signature: TETROMINO PIECES UPGRADE INTO LARGER PIECES via ONE-TIME UPGRADES; puzzle cards give reward pieces upon completion, feeding an engine. Simple, tactile, satisfying. Successfully funded via Kickstarter; earned Kennerspiel-adjacent buzz + strong solo mode.
