| 裏面の説明 | The reverse presents the L-shaped Tetrimino form in its purest expression, divided into four squared cells with rounded corners arranged in the characteristic L configuration — three cells stacked vertically and one cell extending to the right at the base. The surfaces of each cell are polished to a mirror-like finish, while the raised grid lines separating the cells are rendered in frosted relief, creating a strong visual contrast. The overall design faithfully reproduces the iconic Tetris game piece in three-dimensional sculptural form, with no additional inscriptions or devices. |

Niue's arrangement with the New Zealand Treasury allows it to issue legal tender coins with no obligation to actually circulate them — a fiscal technicality that has made the island a favored vehicle for novelty bullion programs since the 1990s. This piece is part of a Tetris-themed series, issued under license from The Tetris Company, which has aggressively protected its intellectual property since the Soviet-era origins of the game at Moscow's Computer Centre in 1984.
The L-tetromino shape dictated an irregular planchet — a non-trivial minting challenge for a one-troy-ounce silver issue.
